Question

2. A cannon was firmly attached to the truck in a steady plane. The cannon was then placed horizontally at an angle of 30 and a 40 kg mass was fired from the cannon at a speed of 300ms-1. The total mass of trucks and cannons is 15000 kg and the truck is on a non-friction surface (C) Determine the rear velocity of the truck on the plane. (B) If it takes 2 × 10 sec for the cannon to come out of the cannon, how much force will the frictionless floor apply to the truck? Mathematically explained​
