Question

What force is exerted on a ball of mass 100g if it accelerates from rest to 30 m/s in 3 seconds?

Force = mass * acceleration
acceleration = change in velocity / time taken

Answer 1

Answer:

$a \: force \: \boxed{f} \: of \: \boxed{ 1N}$

Explanation:

$given : \\ mass \: \boxed{m} = 100g = 0.1kg \\ velocity \: \boxed{v} = 30 {m(s)}^{ - 1} \\ time \: \boxed{t} = 3sec \\ .......................................................... \\ f = ma = \frac{mv}{t } \\ f = \frac{0.1 \times 30}{3} \\ \boxed{f = 1 \: N}$
