Poloy wants to determine the muzzle velocity of his home-made potato launcher. For the experimentsconducted by Poloy on a level test range, the potato launcher muzzle is set to a height of 1.2m from the groundwith a launch angle of 45 degrees with respect to the horizontal. After three trials, the average range of thepotato projectile is 74.3 m on level ground. Determine the muzzle velocity of the potato launcher.

If the ship its stationery and four 5.5 kg shells are fired horizontally and simultaneously in the same direction at 95 m/s , Dertermine the velocity of the recoil and how far will the ship move?
A prop shaft of a heavy-duty truck has two bearings which are positioned at 3 metres from each other. The shaft must rotate at 30 rad/s when the truck travels at the speed of 40 m/s. Such a shaft carries two masses of (MA = 10 kg) and (MB = 5 kg) acting at the extremities of the arms 0.45 m and 0.6 m long,respectively. The planes in which these masses rotate are 1.2 m and 2.4 mrespectively, from the left end bearing supporting the shaft. The angle between the arms is 60°. If the masses are balanced by two counter-masses (named X and Y) rotating with the shaft acting at a radius of 0.3 m and placed at 0.3 m from each bearing centre:2.1.

Principle of Angular Impulse and Momentum To apply the principle of angular impulse and momentum to find final speed and the time to reach a given speed. As shown, ball B, having a mass of 10.0 kg, is attached to the end of a rod whose mass can be neglected. Finding the final speed of the ball If the rod is 0.550 m long and subjected to a torque M=(1.95t2+3.75) N⋅m, where t is in seconds, determine the speed of the ball when t=4.80 s.
