Amass of 20 kg is pulled by a 392 n force in the +x direction along uniform velocity v- 15 m/s. what is the total work done by all forces on the object after s- 10 m? 2. rough surface (u- 0.4) with a find a) the work done by gravity mass is raised at constant speed from 3 m to a height of 32 m 3. as a 30 kg by an external force, f and b) the power required to raise the object as described, in 0.5 seconds. height of 10 calculate the total energy of a 20 kg mass moving upward meters above the ground? at a speed of 26 m/s at a 4. for the previous problem, calculate a) how high the object will be able to climb and b) the velocity of the object at the instant beföre it hits the ground.
