This question is about the motion of a bicycle. A cyclist is moving up a slope that is at an angle of 19° to the horizontal. The mass of the cyclist and the bicycle is 85 kg.
Calculate the component of the weight of the cyclist and bicycle parallel to the slope.
Calculate the normal reaction force on the bicycle from the slope.
At the bottom of the slope the cyclist has a speed of 5.5 m s⁻¹. The cyclist stops pedalling and applies the brakes which provide an additional decelerating force of 250 N. Determine the distance taken for the cyclist to stop. Assume air resistance is negligible and that there are no other frictional forces.
A projectile is fired from level ground with speed at an angle to the ground. Ignoring air resistance, which of the following is a correct expression for the maximum height reached by the projectile?
A stone is thrown at an angle to the horizontal. Ignoring air resistance, the horizontal component of the initial velocity of the stone determines the value of
A uniform rod PQ of weight is attached to a vertical wall at end P by a hinge. A force of magnitude acts on the rod at end Q as shown such that the rod is in equilibrium.

Which of the following diagrams best shows the correct direction of the reaction force at the hinge?
A stone is falling at a constant velocity vertically down a tube filled with oil. Which of the following statements about the energy changes of the stone during its motion are correct?
I. The gain in kinetic energy is less than the loss in gravitational potential energy.
II. The sum of kinetic and gravitational potential energy of the stone is constant.
III. The work done by the force of gravity has the same magnitude as the work done by friction.
The graph shows the variation with time of the velocity of a truck of fixed mass.

What can be deduced from the graph?
