- A 5 kg ball falls from height of 16 m. What willbe potential energy of the ball after 1 second? Use g = 9.8 m/s2A 2-kg brick is thrown downward from a height ?1 = 15 m to ?2 = 10 m. The initial kinetic energy of the brick is ??1 = 25 J. You can use ? = 10 m/s for convenience of calculation. Assume air resistance is negligible, and nothing heats up or uses fuel during the motion of the brick.1. If the system of interest is the brick alone, how much work is done by external forces during this motion?A force of 12.0 N acts on a 4.6 kg object through a parallel distance of 1.6 m. How much work is done on the object? Your Answer:
- The figure below shows a person lifting a box with a mass of 29.8 kg to a height of 1.8 m. Determine the potential energy gained by the the box in Joules.A 40 N object has 80 joules of potential energy. The object is at a height of 0.5 meters. True or falseA race car with a mass of 1850 kg accelerates from rest down a race track at a rate of 21.0 m/s2. If the track is 400m long, what is the gain in kinetic energy of the car when it reaches the end of the track?
- How much potential energy does a person of mass 82kg have if they are standing at the top of a building that is 59.6 m high? sumbit your answer is exponential form.THX!A yoyo of radius R and mass M is released from rest with the string vertical and its top end fixed up a support as shown below.
