- In the figure, a runaway truck with failed brakes is moving downgrade at 107 km/h just before the driver steers the truck up a frictionless emergency escape ramp with an inclination of θ = 20°. The truck's mass is 1.4 × 104 kg. (a) What minimum length L must the ramp have if the truck is to stop (momentarily) along it? (Assume the truck is a particle, and justify that assumption.) Does the minimum length L increase, decrease, or remain the same if (b) the truck’s mass is decreased and (c) its speed is decreased?A cannon of mass 5.12 x 10^3 kg is rigidly bolted to the earth so it can recoil only by a negligible amount. The cannon fires a 81.1-kg shell horizontally with an initial velocity of 549 m/s. Suppose the cannon is then unbolted from the earth, and no external force hinders its recoil. What would be the velocity of a shell fired from this loose cannon?A gymnast jumps straight up, with her center of mass moving at 3.99 m/s as she leaves the ground. How high above this point is her center of mass at the following times?

Neglect friction and air resistance. Solve for the following: 1) Velocity of block after colliding with sphere 2) maximum height reached by the sphere 3) angle θIf a rocket engine ejects gases at a rate of 29 kg/s, how fast must the gaseous exhaust be moving if the thrust produced is sufficient to allow a 2.7 x 105 kg rocket to rise slowly from the earth when aimed straight up?
