Question

a force of 15 n is applied upon a body of mass n the body moves in a straight line with its speed increasing by 10m/ s every 2sec calculate mass of the body

Answer 1

force=mass.acceleration

$f = ma \\ a = 10 \div 2 = 5m \: \: per \: second ^{2} \\ \\ 15n = m \times 5 \\ m = 15 \div 5 = 3kg$

Answer 2

Answer:

answer is 3 kg

Explanation:

f =ma

m=f/a

m=15/3

m=3 kg
