Answer:
answer
A force is applied on a body of mass 20 kg moving with a velocity of 40 ms^-1 . The body attains a velocity of 50 ms^-1 in 2 seconds. Calculate the work ...
Force = m (v - u )t = m · a Displacement = (v^2-u^2)2a Word done (W) = Force × Displacement = m · a · (v^2-u^2)2a W = 12 m (v^2 - u^2 ) W = 12 ... More
