5. 1) As shown in the image below, the snowmobile has a weight of 259 lb, centered at G1, while the rider has a weight of 154 Ib, centered at G2. If the acceleration is a = 13.5 ft/s?, dimensions are di = 0.9 ft, d2 = 0.4 ft, d3 = 1.6 ft, d4 = 1.6 ft, and height h of G2 of the rider is 1.8 ft, determine the normal reaction force under the front skid at point B. Assume there is only traction (horizontal) force under the rear tracks, but no friction force under the front skid. Please pay attention: the numbers may change since they are randomized.

A motorcycle and rider have a combined mass of 350kg. The vehicle's velocity is 100 km/hr. The rider is to go up a hill incline of 10 meters. The wheels each have a mass of 20 kg and a diameter of 500mm. The wheel design consists of 6 spokes with a mass of 0.5 kg for each spoke. a. Determine the vehicle's velocity at the top of the hill, assuming it was a rolling vehicle with engine being turned off. a. Indicate the vehicle's velocity at each meter through the climb. b. Explain the transfer energy and how this affects the behaviour of the system. At another point in its journey, the motorcycle and rider travel at 80 km/h around a left-hand bend of radius 30m. Calculate: a) The angular velocity of each wheel. b) The moment of inertia of each wheel. c) The angular momentum of the wheel prior to entering the bend. d) The magnitude of the gyroscopic torque produced on the bike as the rider is driving around the bend.
