Question

*A force of 20 N is applied on an object of mass 200 gram at rest for 6 second only how much velocity will the object achieve.*​

Answer 1

Answer:

Newton's second law of motion is F = ma, or force is equal to mass times acceleration. Learn how to use the formula to calculate acceleration. Created by Sal Khan.

Answer 2

Force =m (v−u)/t =m⋅a

Displacement =

2a(v^2−u^2 )

Word done (W) = Force × Displacement

=m⋅a⋅ (v^2−u ^2)/2a

W = 1/2m(v ^2−u ^2 )

W = 1/2×20×(2500−1600)

= 1/2 ×20×900

=9000J

Therefore, the work done to attain the final velocity is 9000J
