Answer:
2.8 m 7.4 m/s
Explanation:
write all the values then use the equations of motion to find the distance and speed. please see attached photo
Answer:
given,
children on left shore pulls the rope by 3 N
Children on the right shore pulls the rope by 2 N
speed of the box = 3 m/s
a) Power = Force x Velocity
Power = 3.0 N * 3
Power = 9 Watt
Power = 2.0 N x 3
Power = 6 Watt
b) Net Force = 3.0 N - 2.0 N = 1.0 N
Net Power = 1.0 x 3 Watt
Net Power = 3 Watt
c) net force is acting on the box and at an instant velocity is given so, when the body moves it will accelerate and velocity will change so, the value of part A and B will also change
