A-LevelPhysicsKinematicsMay/June 2018Paper 1 Q61 Mark
A projectile is launched at an angle to the horizontal at time t = 0. It travels over horizontal ground, as shown. [Diagram] Assume that air resistance is negligible. Which graph best shows the variation with t of the speed of the projectile from when it is launched to when it lands on the ground?
AGraph of speed vs time showing a constant speed.
BGraph of speed vs time showing speed decreasing linearly then increasing linearly (V-shape).
CGraph of speed vs time showing speed decreasing then increasing in a U-shape curve.
DGraph of speed vs time showing speed decreasing linearly then increasing linearly (V-shape).
