Question

A 1500 kg car traveling due east at 20

m/s slows to a stop in 5.0 seconds. What is the impulse?

Answer 1

30,000N/S this is because impulse =force*time therefore to get the force mass*acceleration. Using Newton’s first law of motion to find acceleration ie. V-u/t =-4m/s^2
Equating to the question 1500*4=6000N *5=30,000N/S
