Question 4

In this question use g=9.8g = 9.8g=9.8 m s−2^{-2}−2.

A ball is kicked from a point on horizontal ground with velocity (6i+14j)(6\mathbf{i} + 14\mathbf{j})(6i+14j) m s−1^{-1}−1, where i\mathbf{i}i is horizontal and j\mathbf{j}j is vertically upwards. The ball is modelled as a particle moving freely under gravity, and air resistance is modelled as negligible.

a.

Find the time taken for the ball to return to the ground.

[2]
b.
