Answer:
-67 m/s
Explanation:
We are given that
Mass of ball,m=0.4 kg
Initial speed,u=14 m/s
Impulse,I=-32.4 N-s
Time,t=27 ms=
We have to find the mass's velocity in the x- direction.
We know that

Substitute the values




Answer:
the power output P = 1484 W
Explanation:
Power P = Force× speed
Given that motor of a battery-powered scooter can maintain a speed of 5.3 m/s by providing a force of 280 N.
Therefore,the power output of the motor P = 280×5.3 = 1484 W
Hence, the power output P = 1484 W
