Question

When the velocity of a body of mass 100 kg increases, the body is said to be accelerating. If the velocity increases at a uniform rate 5 m s¹ to 10 m s¹ in 5 s, the acceleration is said to be uniform. The force acting on the body is equal to​

Answer 1

$a = \frac{v - u}{t} \\ a = \frac{10 - 5}{5} \\ a = 1 \: {ms}^{ - 2}$

Now,

F = ma

F = 100 x 1 N

F = 100 N

Therefore the force acting on the body is 100N The magnitude of this force is equal to the mass of the object.
