2-Kinematics Structured Questions with Solutions

2-Kinematics Structured Questions with Solutions

1.) A shell is fired from a hill 400 m above the ground at an angle 30° to the horizontal with a speed of 45.0 m s-1. How far from the hill and at what angle will the shell hit the ground? [2]



2.)

Is it possible for a body to be at rest and yet be accelerated? State an example if yes. [2]

Answer:
Yes. An example will be when an object is thrown vertically upwards and reaches the peak of its motion. The velocity will be momentarily zero while acceleration is the gravitational acceleration.
