Question

How much force in Newtons is required to accelerate a shotput weighing 4kg at 21 m/s2?

Answer 1

`\Huge{\boxed{84 N}}`

Step-by-step explanation:

The amount of force required here can be found by using the formula

force = mass × acceleration

where

mass is in kg

acceleration in m/s²

From the question

mass = 4 kg

acceleration= 21 m/s²

We have

force = 4 × 21 = 84

We have the final answer as

84 N
