Question

if a force of 30 N is applied on a body of mass 15 kg then what will be the acceleration​

Answer 1

For the total 3m distance: F=ma

a=

m

F

=30/2=15m/s

Answer 2

Answer:

Here is your answer mate

Explanation:

Force = mass × Acceleration

Force =30N

Mass=15kg

Acceleration =30/15

2m/sec^2
