A truck is traveling south at a speed of 70 km/h toward an intersection. A car is traveling east toward the intersection at a speed of 80 km/h. The relative velocity of the car to the truck is estimated as

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. What is the effect and why is it important to calculate the gyroscopic…

A railroad car having a mass of 15000 kg is coasting at 1.5 m/s on a horizontal track. At the same time another car having a mass of 12000 kg is coasting at 0.75 m/s in the opposite direction. If the cars meet and couple together, determine the speed of both cars just after the coupling.

An athlete is holding 36 lb of weights at a height of 6 inches above the stack as shown. To lower the weights, she applies a constant force of 5 lb to the handle. Determine the velocity of the weights immediately before they hit the stack.

A 4-kg package is released from rest at point A and travels down the conveyor shown. Portions AB and CD are parallel to each other. Neglect friction and any other energy loss. Given: L = 4.5 m. Determine the acceleration of the package at A.

A ball is thrown vertically upward with a speed (vo) of 15 m/s at an initial position of so= 10 m.  The ball is subjected to a constant downward acceleration of 9.81 m/s2. Determine the maximum height, smaxreached by the ball. Determine the time of flight when it returns to its original position. Determine the time of flight when it hits the ground. Determine the velocity just before it hits the ground. Check your answer using a different equation. Plot v(t) and s(t) from t = 0 to the time when the ball hits the ground.
