Question

which would require a greater force- accelerating a 2 kg mass at 5m/s2 or a 5 kg mass at 3m/s2?​

Answer 1

Mass m1=2kg

m2=5kg

acceleration a1=5m/s2

a2=3m/s2

force

F1=m1×a1

=2×5=10N

F2=m2×a2

=5×3=15N

F1<F2

10N<15N

therefore accelerating a 5kg would require greater force

Answer 2

5kg of 3m/s2 has the greater force than the other
