Question

A rocket has a mass of 15 kg and travels a distance of 250 meters in 13 seconds before it explodes.

What is the velocity of the rocket?
And
What is the momentum of the rocket?

Answer 1

1. Velocity = 19.2m/s

2. Momentum = 288 Kg/ms-¹

Step-by-step explanation:

1. The velocity of the rocket can be calculated by using the formula:

V = d/t

Where v = velocity/speed (m/s)

d = distance (m)

t = time (s)

Based on the provided information, d = 250m, t = 13s

v = 250/13

v = 19.231

v = 19.2m/s

2. The momentum of the rocket can be calculated thus:

p = m × v

Where;

p = momentum (Kg/ms-¹)

m = mass (kg)

v = velocity (m/s)

Based on the information, we have v= 19.23m/s, m = 15kg

p = 15 × 19.2

p = 288 Kg/ms-¹
