Question

Please help kind people if you know physics, it is very important to me!

1.(a) What is the minimum impulse needed to give a 275-kg motorcycle and rider a velocity of 20.0 m/s [W] if the motorcycle is initially at rest? (b) If the wheels exert an average force of 710 N [E] to the road, what is the minimum time needed to reach a velocity of 20.0 m/s [W]?

2.A 275-kg snowmobile carrying a 75-kg driver exerts a net backward force of 508 N on the snow for 15.0 s.

3.A cannon mounted on wheels has a mass of 1380 kg. It shoots a 5.45-kg projectile at 190 m/s [forward]. What will be the velocity of the cannon immediately after firing the projectile?
