Starting from rest, a 1.7x104 kg flea springs straight upward. While the flea is pushing off from the ground, the ground exerts an average upward force of 0.35 N on it. This force does 2.7x10-4 J of work on the flea. (a) What is the flea's speed when it leaves the ground? (b) How far upward does the flea move while it is pushing off? Ignore both air resistance and the flea's weight. (a) Number i (b) Number i Units Units

While the stone is moving upwards the gravitational force does positive work on it and the gravitational potential energy increases. the gravitational force does positive work on it and the gravitational potential energy decreases. the gravitational force does negative work on it and the gravitational potential energy increases. O the gravitational force does negative work on it and the gravitational potential energy decreases.
true or false? When an object slides across a surface and comes to a stop, the amount of energy removed is equal to the amount of work performed by friction.
A horizontal spring is stretched 10 cm and then released from rest. Will the spring ever stretch a distance greater than 10 cm? Explain why or why not using the idea of energy conservation.
Suppose that a certain spring has spring constant k = 0.08 N/m (that’s Newtons per meter). How much work must be done to stretch the spring by 0.5 m past its equilibrium point? Your answer will end up in units of N*m .
A person pulls a 75-kg box 20 m along a horizontal floor by a constant force Fp = 125 N, which acts at a 42 degree angle. The floor is not smooth and exerts a friction force of Ff = 65 N.

A 10 kg barbell is rolling down a hill. There is no friction or air resistance acting on it, only the force of gravity. If it starts out moving 2 ms1, and ends up moving 7 ms1, then how much work does gravity do on it?
A 3 kg block is sliding across a horizontal surface. The initial speed of the block is 4 m/s, but because of friction the block’s speed will decrease at a constant rate (i.e., constant acceleration) until the block finally comes to a stop after sliding 8 m. What is the average power (in W) supplied by friction as the block slows to a stop?
A car with the mass m=1600kg coasts down an incline from an initial height of h=7m with an initial speed v0=15m/s. When it reaches the bottom of the incline its speed is 20m/s. How much work did friction do on the car? This is the full question. No acceleration given. Assistance please.
During terrible weather at a ski-flying world championship, a ski jumper tried to adjust for bad conditions midway down the ramp but completely lost control and tumbled wildly off the side at its bottom into a scattering crowd. The 73-kg jumper left the ramp about 45 m lower than his starting position. After hitting the ground, the jumper crashed wildly and descended down the hill another 20 vertical meters before coming to rest. Here, friction cannot be ignored. Calculate the total work done on the ski jumper to bring him to rest. Round the final answer to the nearest whole number.
A 12.0 kg box is given an initial push that starts it sliding across the floor. It eventually comes to a stop. If the box has an initial velocity of 3.5 m/s, how much work is done by friction to cause it to come to a stop? (Yes, you are correct, you do not know the coefficient of friction.)
