A car moves along a level road.
The diagram shows all of the horizontal forces acting on the car.
Which statement is correct?
The car is slowing down.
The car is speeding up.
The car is moving at a constant speed.
The car is moving backwards.
Which force and distance produce the smallest moment about a pivot?
a 6.0 N force at a perpendicular distance of 4.0m from the pivot
a 7.0 N force at a perpendicular distance of 6.0 m from the pivot.
a 10 N force at a perpendicular distance of 4.0 m from the pivot
a 12 N force at a perpendicular distance of 3.0 m from the pivot.
The diagram shows a tug-of-war between team X and team Y. The arrows show the forces exerted by the teams on the rope.
What is the size of the resultant force on the rope and in which direction does the resultant force act?
size of resultant force = 75 N; direction of resultant force = to the left
size of resultant force = 75 N; direction of resultant force = to the right.
size of resultant force = 725 N; direction of resultant force = to the left
size of resultant force = 725 N; direction of resultant force = to the right.
An object of mass 50 kg accelerates from a velocity of 2 m/s to a velocity of 10 m/s in the same direction. What is the impulse provided to cause this acceleration?
250 Ns

2500 Ns
A T-shaped girder is placed on the ground in position X. it is then turned over to position Y. What happens to the force on the ground and what happens to the pressure on the ground?
force increases, pressure increases
force increases, pressure remains the same
force remains the same, pressure increases
force remains the same, pressure remains the same
A cyclist travels down a hill from rest at point X, without pedalling. The cyclist applies his breaks and the cycle stops at point Y. which energy changes have taken place between X and Y?

Gravitational potential -> thermal (heat) -> kinetic
kinetic -> gravitational potential -> thermal (heat)
kinetic -> thermal (heat) -> gravitational potential
A skier walks from the bottom of a ski slope to the top and gains 10,000J of gravitational potential energy. She skis down the slope. At the bottom of the slope, her kinetic energy is 2000J. How much energy is dissipated in overcoming friction and air resistance as the skier moves down the slope?
