Question

What force is needed to accelerate a 36kg child on a sled at 1.25m/s?

Answer 1

According to Newton's second law,


F = ma

That is, Force = mass × acceleration


Here, we know the mass and acceleration so simply we can calculate the force


F = ma

=> F = 36 × 1.25

=> F = 45N

Your answer :-

$\fbox{45N}$


Additional info :-


While calculatting force, remember that the mass and acceleration is given in kg and m/s². If not, then convert them into kg or m/s²



Hope it helps dear friend ☺️✌️
