Trajectory Calculations | MCQs

Explanation

Ball falls 20m, so time taken is found using:

s = 1/2 gt²

20 = 1/2 × 10 × t²

t = 2s

Vertical velocity when it hits the ground:

v_y = gt = 10 × 2 = 20 m/s

Since it hits at 45°, v_x = v_y = 20 m/s

Explanation

Projectile motion is a type of two-dimensional motion where an object moves under the influence of gravity, with a constant acceleration of g (9.8 m/s²).

It involves a combination of horizontal motion with a constant velocity and vertical motion with a constant acceleration, resulting in a curved trajectory.
