5) A 2,200 kg car goes flying off a highway overpass in a Hollywood movie. How much potential energy does the car have if the overpass is 25 meters high?

While I can kick a soccer ball so that it has a speed of 10 m/s, David Beckham can kick a  ball so that it has a speed of 45 m/s. How many times greater is the Kinetic Energy of the ball kicked by Beckham than the ball kicked by me?

a) how much net work is required to accelerate a 1135-kg car from 18 m/s to 40 m/s? b) how much net work is required to accelerate a 955-kg car from 17 m/s to 45 m/s? c) how much net work is required to accelerate a 1089-kg car from 16 m/s to 36 m/s?

6. If a 8.5 kg ball is thrown upwards and the potential energy gained by the ball is 1.3328 x 10^3 J. What high is the ball thrown?

4. How many joules of energy does a 100-watt light bulb use per hour? How fast would a 70-kg person have to run to have that amount of kinetic energy?

A hiker of mass 73 kg is going to climb to the top of Mount Tam, which has an elevation of 2,574 ft. a) If the hiker starts climbing at an elevation of 545 ft, what will their change in gravitational potential energy be, in joules, once they reach the top? Assume the zero of gravitational potential energy is at sea level.  b) Repeat the above calculation for the change in gravitational potential energy, but assume the gravitational potential is zero at the top of the mountain.

How much work is done by boy pulling his sister 33m in a wagon as shown in the figure below? (A) no friction acts on the wagon and mass of wagon and girl is 35kg (assume d=33m and F=56N.) (B)Assume a coefficient of friction of 0.025. How much word is done by: (i) The net force (ii) friction. (Iii) normal force
