Answer:
Mass m = 7.5 × 10^(-4) Kg
Time t = 0.5 sec
Length l = 0.1 m = 10 cm
Explanation:
1 dyne = 1×10^(-5) N
1 dyne = 1×10^(-5) Kgm/sec
1 cm/sec^(2) = 0.01 m/sec^(2)
# Force; F = ma > a = F/m
> a = [30×10^(-5)] / [40×(0.01)]
> a = [30×10^(-5)] / [0.4]
> a = 7.5×10^(-4)
# Time; v = at > t = v/a
> t = (20×0.01) / (40×0.01)
> t = 0.5 sec
# Length; l = vt
> l = (20×0.01) × 0.5
> l = 0.1 m = 10 cm
