Answer:
Then its acceleration is zero.
Explanation:
Velocity → Uniform → Constant
→ Change in Velocity = 0
A=
= (v=m)
a=0
Answer:
<em>50 m/s</em>
<em></em>
Explanation:
In a projectile motion, acceleration is only on the vertical plane, that is, the vertical velocity is the only velocity component that undergoes acceleration under gravitational force. The horizontal component of velocity dos not change with time, and hence is the same as the initial velocity of the projectile.
