Question

3) Consider a rocket in deep space (so it's weightless) with thrusters that generate a forward

force of +500. N. If the acceleration it experiences in this scenario is +5,00 , calculate:
a) the mass of the rocket,
b) its displacement in the first 100 s, assuming it starts from rest.

Answer 1

a). F= m a

500 N = (m) (5.00 m/s^2)

m = 100 kg

b). Accelerating body covers distance of

D = 1/2 a T^2

D = 1/2 (5.00 m/s^2) (100 s)^2

D = 25,000 meters

Note: I'm pretty sure the acceleration is typed wrong in the question. If so, then these answers won't be correct.
