Question 1 Report
A constant force of 5N acts for 5 seconds on a mass of 5kg initially at rest. Calculate the final momentum
Answer Details
Impulse = momentum
Impulse = Force (f) × time (t)
Momentum = mass (m) × velocity (v)
? Ft = Final momentum - initial momentum
FT = mv - mu
Since it is initially at rest u = 0
? 5 × 5 = mv ? m(0)
25 = mv
? Final momentum = 25kgms?1
