Question

What would require greater force? Accelerating 10 g mass at 5 m/s^2 or 20 g at 2 m/s^2 1) 10g 2) 20g 3) both would require same force 4) acceleration is not produced by this force

Answer 1

Answer:

CASE I

m = 10g = 0.01kg

a = 5 m/s^2

F=ma

= 0.01 × 5

= 0.05 N

•CASE II

F = ma

m = 20g = 0.02kg

a = 2 m/s^2

F = ma

= 0.02 × 2

= 0.04N

ANSWER IS CASE 1
