Answer #1

If a par is projected at fixed speed, it will travel the furthest horizontal distance if it is projected at an angle of 45° to the horizontal. This is because the maximum sin2a can be is 1 and sin2a = 1 when a = 45°.

Horizontal range for a projectile motion is

here, angle is 45 degrees, u = 2.04 m/s, g = 9.8m/s^2

So,  the maximum horizontal distance the rock could travel is 0.4242 m. Ans.

A large catapult, standing on a flat field, throws a rock into the air with initial speed 17.8 m/s at an angle 33.1o to the horizontal. At the same time, there is a wind blowing parallel to the ground, causing the rock at accelerate at 0.703 m/s2 horizontally. Ignoring friction: find the horizontal distance, in m, that the rock travels before it hits the ground.
