PART I
1. Together, 2 students exert a force of 825 N in pushing a car a distance of
35 m.
20
a) How much work do the students do on the car?
b) If the force was doubled, how much work would they do pushing the
car the same distance?
2. A rope is used to pull a box 15.0m across the floor. The rope is held at an
angle of 15° with the floor and a force of 628 N is applied to the rope. How
sda much work does the force on the rope do?
sd to Ioms
3. A 1600-kg car travels at a speed of 12.5 m/s. What is its kinetic energy?
2i oss sd os bonish
4. A racing car has a mass of 1525 kg. What is its kinetic energy if it has a
speed of 108 km/h?
(Note: Convert 108 km/h to m/s)
5. A ball of mass 0.5 kg has 100 J of kinetic energy. What is the velocity of
the ball?
6. A ball traveling at 30 m/s has 900 J of kinetic energy.What is the mass of
the ball?
7. How much potential energy does Mark with a mass of 60.0 kg gain when
he climbs a gymnasium rope a distance of 3.5 m?
8. The world record for pole vaulting is 6.15 m. If the pole vaulter's
gravitational potential is 4942 J, what is its mass?
9. In 1993, a Cuban athlete Javier Sotomayor set the world record for the
high jump. The gravitational potential energy associated with Sotomayor's
jump was 1970 J. If Sotomayor's mass is 80.0 kg, how high did he jump?
