The amount of work done to lift an object is equal to the force applied multiplied by the distance over which the force is applied. Without information about the force or mechanism used to lift the beam, it is not possible to calculate the work done.
The final velocity can be calculated using the formula final velocity = initial velocity + (acceleration * time). Since the ball starts at rest, the initial velocity is 0. The final velocity = 0 + (acceleration * 5). To find the acceleration, you can use the formula acceleration = (final velocity - initial velocity) / time. The final velocity is unknown, but we just calculated the final velocity is equal to 5 times the acceleration, so acceleration = (final velocity - 0) / 5. Substituting the final velocity = 5 times the acceleration into the acceleration equation, we get acceleration = (5 * acceleration - 0)/5. Solving for acceleration, we get acceleration = 1 m/s^2. The final velocity is 5 m/s.
The acceleration of the object can be calculated using the formula F = ma, where F is the force applied, m is the mass of the object, and a is the acceleration. Rearranging the formula, we get a = F/m. Plugging in the values, we get a = 50N / 0.2kg = 250 m/s^2.
a) The work done is calculated by the formula W = Fd*cos(theta), where F is the force, d is the distance, and theta is the angle between the force and the direction of motion. Plugging in the values: W = 60 N * 250 m * cos(40 degrees). b) The work done is 0 because the force is applied at an angle above the horizontal, so part of the force is directed vertically and does not contribute to the displacement of the suitcase in the horizontal direction, hence no work is done in the horizontal direction.
Safe depth for a U-Boat was between 180-250m deep. Any more and they ran the risk of being crushed by the oceanic pressure.
250m is equal to 0.25 kilometers.
