Aball is thrown with an initial velocity of 20 m/s at an angle of 60° above the horizontal. if we can neglect air resistance, (a) what is the horizontal component of its instantaneous velocity at the exact top of its trajectory? (b) how long is the ball in flight before it hits the ground? (c) how far has the ball traveled in the horizontal direction when it lands?

(a) the horizontal component of its instantaneous velocity at the exact top of its trajectory is 10 m/s.

(b) The time of flight of the object is 3.53 s

(c) The horizontal distance traveled by the ball when it lands is 35.35 m.

The given parameters;

(a)  The horizontal component of its instantaneous velocity at the exact top of its trajectory.

the initial horizontal component of the velocity;

At the top of its trajectory, the velocity is equal to its initial value.

Thus, the horizontal component of its instantaneous velocity at the exact top of its trajectory is 10 m/s.

(b) The time of flight of the object is calculated as;

(c) The horizontal distance traveled by the ball when it lands;
