What impulse is needed for a plane mass 78 tonne to change its velocity by 65 m s-1? Give your answer to the nearest whole number.

Question

BlackTom AI · Accepted Answer

The problem asks for the impulse required to change the velocity of a plane with a given mass by a certain amount, which is a classic impulse–momentum relationship.
First, convert the mass from tonnes to kilograms: 78 tonnes equals 78,000 kg, since 1 tonne = 1000 kg.
Next, identify the change in velocity: Δv = 65 m/s.
Impulse J is the change in momentum, J = Δp = m · Δv.
Compute the product: 78,000 kg × 65 m/s = 5,070,000 kg·m/s, which has the same units as impulse (N·s).
Thus, the impulse required is 5,070,000 N·s. If you’re asked for a nearest whole number in standard units, this would be 5,070,000 (no decimals needed).
