The force required to stop a body of mass 10 ~kg moving along a straight line path with a velocity of 10 ~ms ⁻¹ in a time of 10 ~s is
Options
- A10 ~N
- B1000 ~N
- C100 ~N
- D1 ~N
Correct answer
A. 10 ~N
Step-by-step solution
Mass, m =10 ~kg Initial velocity, u=10 ~m / s Time, t =10 sec final velocity, V =0 using Newton's IInd law aligned & F=m a=m ( V-u t ) & = 10 10 10 =10 & F=10 N aligned
