Question

(b)
Which would require a greater force : (a) accelerating a 10 gm
mass of 5 m's or (b) a 20 gm mass at 2 m/s??
[convert mass into kg]​

Answer 1

Step-by-step explanation:

Solution :

(i) In first case: Force, F=m×a

=101000kg×5m/s2

=0.05N

(ii) In second case : Force,F=201000kg×2m/s2

=0.04 N

Thus, a greater force of 0.05 N is required for accelerating a 10 g mass.
