Question

A Canyon ball is fired from the ground level in angle of 35 from the ground at a speed of 150 m/s ignore air resistance calculate the horizontal and vertical components of its initial velocity

Answer 1

The velocity, 50 m/s, has two components - vertical and horizontal velocities.

The vertical component = 50 sin 30 = 25 m/s

The horizontal component = 50 cos 30 = 43.3 m/s

(a)  Let t be the time taken for the vertical component to reach its peak from initial velocity = 25 m/s to its final velocity = 0.

     Using the linear motion equation v = u - gt

     0 = 25 - 10t

     t = 2.5 s

    Time taken to go up and down = 5 s

    Time to hit the ground = 5 s

(b) Horizontal distance dealt x = 43.3 * 5 = 216.5 m

This is not the correct answer, but explains the problem thoroughly.
