Answer:
12.5 m/s
Step-by-step explanation:
Given that,
The initial horizontal and vertical components are 12.50 m/s and 21.70 m/s, respectively.
We need to find the horizontal velocity of the ball at position C.
It is a case of projectile motion. We know that in case of projectile motion, the horizontal velocity of the projectile remains the same while vertical velocity varies. It can be very clear that the horizontal velocity at C is 12.5 m/s.
