Question

A hover craft also known as a air cushion vehicle glides on a cushion of air allowing it to travel with equal is land or water. The first commercial hovercraft to cross the English channel the V. A-3 had a average speed of 26.7 M/S. Its momentum at the speed was 4.8×10^4 KGM/S. What was the mass of the V. A-3?

Answer 1

Answer: M = 1797.75 kg

Explanation:

given parameters are;

speed V = 26.7 M/S.

momentum P = 4.8×10^4 KGM/S.

What was the mass of the V. A-3?

Momentum P is the product of mass and velocity. That is, P = MV

Substitute V and P into the formula

4.8×10^4 = 26.7 × M

Make M the subject of formula

M = 4.8×10^4/ 26.7

M = 1797.75 kg

Therefore, the mass of the V. A-3 was 1797.75 kg
