Q1. A projectile is shot from the edge of a cliff 126m above ground level with an initial speed of 65.7 m/s at an angle of 37.0° with the horizontal. (a) Find out the time taken by the projectile to hit point P at ground level, (b) find out the range X of the projectile as measured from the base of the cliff. At the instant just before the projectile hits point P, find (c) horizontal and the vertical components of its velocity, (d) magnitude of the velocity, and (e) the angle made by the velocity vector with the horizontal. (J) Find the maximum height above the cliff top reached by the projectile.

Q2. A helicopter is rising at 4.60 m/s when a bag of its cargo is dropped. The bag falls for 2.50 s. (suppose that the positive direction is upward.)

(a) What is the bag's velocity?

(b) How far has the bag fallen?
