Question

(b) Which would require a greater force accelerating a 5 kg mass at 5 ms?
or a 3 kg mass at 7 ms??​

Answer 1

Explanation:

Force F=ma

(1) : F1 =m1 a 1

=2×5=10 N

(2) : F 2=m 2 a 2

=4×2=8 N

So, 2 kg will require greater force.

Answer 2

Answer: As F=ma

So the product for first scenario is 25 N

While product for second one is 21 N, so clearly the 5 kg body would require a greater Force
