14.715 m/s.
This is worked out by knowing that gravity will accelerate a body at 9.81 (m/s)/s. The average velocity is the speed at 3s plus the speed at 0s divided by 2.
Speed at 0s = 0 x 9.81 = 0 m/s
Speed at 3s = 3 x 9.81 = 29.43 m/s
(29.43 + 0) / 2 = 14.715 m/s.

What is a skydivers average velocity for the first 3 seconds?
The average velocity for the first 3 seconds of a skydiver's free fall would depend on the initial speed, air resistance, and gravitational acceleration, but generally, it could be around 55-60 m/s.
What is the distance that the object travels in the first 5 seconds?
To find the distance traveled in the first 5 seconds, we multiply the average velocity by the time traveled. If the object's velocity is constant, this distance is equal to the velocity multiplied by the time.
What is its average acceleration over the first 5.1s of its motion?
To find the average acceleration over the first 5.1 seconds of motion, divide the change in velocity over that time period by the time taken. Calculate the final velocity minus the initial velocity over 5.1 seconds to find the average acceleration.
What is the velocity of a car that is traveling -50 meters in 5 seconds then 10 meters in 5 seconds?
The average velocity for the entire trip can be calculated as the total displacement over the total time. First find the total displacement (final position - initial position): -40 meters. Then, calculate the total time: 10 seconds. Finally, divide displacement by time to find the average velocity: -4 m/s.
The magnitude of the acceleration of the during the first 3 seconds is?
The magnitude of acceleration during the first 3 seconds can be determined by calculating the change in velocity over that time period. By dividing this change in velocity by the time interval (3 seconds), you can find the average acceleration magnitude during that time.

The body travels 2mts in first 2 seconds and 2.2mts in next four seconds what will be the velocity at the seventh second?
heres the average 2.2 seconds
What is the velocity of 10m 12h?
0.0002315 m/s OR 0.0008333 km/hour The velocity of an object is the rate of its change in position in a certain direction. Velocity is a vector quantity; this means that it has both a magnitude and direction. To find the average velocity of an object in motion, the following equation is used: average velocity= (total displacement)/ (total time elapsed) The SI units of velocity are "m/s" , but any distance unit over any time unit is also acceptable. Solving for the velocity asked for: First let's change hours to seconds: (12 hours ) x (6o minutes/hour )x (60 seconds/minute)= 43200 seconds Finding the velocity: average velocity= (displacement)/ (time)= 10m/ 43200 seconds= 0.000231481 m/s

14.715 m/s. This is worked out by knowing that gravity will accelerate a body at 9.81 (m/s)/s. The average velocity is the speed at 3s plus the speed at 0s divided by 2. Speed at 0s = 0 x 9.81 = 0 m/s Speed at 3s = 3 x 9.81 = 29.43 m/s (29.43 + 0) / 2 = 14.715 m/s.
True or false Skydivers spend the first several seconds of their jump in free fall?
True. Every second of a jump is in freefall from when the jumper leaves the plane until the deployment sequence begins.
Do skydivers spend the first several seconds of their jump in freefall?
Yes, skydivers do spend the first several seconds of their jump in free fall. They do not usually open their parachutes until they are about 2,000 feet above the ground. Opening the parachute too soon might cause the parachutist go extremely way off course or result in an updraft that will cause injury.
Is it possible for the average velocity of an object to be zero during some interval even thought its average velocity for the first half of the interval is not zero explain and cite an example?
Yes, it is possible for the average velocity of an object to be zero during some interval, even if its average velocity for the first half of the interval is not zero. This can occur if the object moves in opposite directions with equal distances during the two halves of the interval. For example, if a car moves 3 miles east in the first half of an hour and then moves 3 miles west in the second half of an hour, its average velocity for the entire hour would be zero.
