Question

which would required a greater force,accelerating a 10 g mass at 5m/s2 or a 20 g mass at 2m/s2?

Answer 1

the first may require more force that is 50J

Answer 2

FORCE = MASS * ACCELERATION
THEREFORE,
FORCE =10g*5m/S2
=50 Newton

AND, FORCE=20g*2m/S2
=40newtons
SO THE GREATER FORCE WILL BE NEEDED BY THE FIRST OBJECT.....
