A ball is fired from a toy gun with an initial speed of 7.00 m/s with the gun aimed at 300 upward with respect to the horizontal. The point of firing is 1.32 m above the horizontal floor. What is the horizontal component of the ball's initial velocity?

6.0621 m/s

Explanation:

we all know that horizontal component of the velocity in projectile motion is

= u cosα

u= initial speed of 7.00 m/s of the gun.

α = angle of the initial velocity with the horizontal = 30°

therefore, horizontal component of the ball's initial velocity = 7×cos30°
