Answer:
300
Explanation:
work done=force×displacement
=60*5=300J
power=work done/time
=300/3=100Js
Answer: The acceleration of 28 Kg object will be 2
Explanation: Force acting on an object is defined as mass times acceleration acting on it.
Mathematically it is defined as:
Force = mass acceleration
F = 8 7 = 56 N
If the same force is acting on a 28 Kg object then the acceleration of the object will be equals to force to mass ratio.
Acceleration = = 2
