Answer:
1. Velocity = 19.2m/s
2. Momentum = 288 Kg/ms-¹
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
