Question

A motorbike is initially at rest driven by a force of 1000 N if the mass of the bike is 50 kg then calculate the kinetic energy at the end of 5 sec​

Answer 1

Explanation:

F = 1000 N

Mass=50 kg

Acceleration=1000/50

=20 m/sec^2

It was initially at rest so

u(initial velocity)= 0

Applying v = u + at

v = 0 + 100

v= 100 m/sec

kinetic energy=1/2(mv^2)

=1/2(50 × 10000)

=250000 J
