Question

(i) Force required in accelerating a 3 kg mass at 5 m/s² and a 4 kg mass at 4 m/s, will be
(a) zero in both the cases
(6) same in both the cases
(c) greater for 3 kg mass at 5m/s2
(d) greater for 4 kg mass at 4 m/s2​

Answer 1

Answer:

(d) greater for 4 kg mass at 4 m/s2

Explanation:

Because as we know that F = m×a and the mass of the object is 4 and the acceleration us also 4 which is equal to 16N Force. That is greater than the force of 15N of object A.
