Question

The velocity of a 0.25kg model rocket changes from 15m/s [up] to 40m/s [up] in

Answer 1

The force the escaping gas exerts of the rocket is 10.42 N.

Force escaping gas exerts

The force the escaping gas exerts of the rocket is calculated as follows;

F = m(v - u)/t

where;

• m is mass of the rocket
• v is the final velocity of the rocket
• u is the initial velocity of the rocket
• t is time of motion

F = (0.25)(40 - 15)/0.6

F = 10.42 N

Thus, the force the escaping gas exerts of the rocket is 10.42 N.
