A 5 kg weight is accelerated from rest to [tex]$20 m / s$[/tex] in 2 seconds. What is the force acting on the body?

Asked by narayan2078pandey

Answer (2)

The force acting on a 5 kg weight accelerated from rest to 20 m/s in 2 seconds is 50 Newtons (N). This is calculated using Newton's second law, where force equals mass times acceleration. The acceleration is found to be 10 m/s².

Find the acceleration as Δv/Δt = 20 m/s / 2 s = 10 m/s^2
Then Newton's law states
F = m*a
F = 5 kg * 10 m/s^2 = **50 Newtons ** ;
