The constant force required is 17.6 N
Explanation:
Given-
Mass, m = 0.55 kg
Initial speed, u = 0
Final speed, v = 8 m/s
Time, t = 0.25 s
Force, F = ?
We know,
Force = mass X acceleration
F = 0.55 X [tex]\frac{v}{t}[/tex]
F = 0.55 X [tex]\frac{8}{0.25}[/tex]
F = 17.6 N
Therefore, the constant force required is 17.6 N
The constant force exerted on the ball is 17.6 N
The first is to calculate the acceleration
= velocity/time
= 8/0.25
= 32 m/s
Force= mass × acceleration
= 0.55 × 32
= 17.6 N
Hence the constant force exerted on the ball is 17.6 N
