Read the scenario below very carefully. You just went to the humane shelter and adopted a 45 kg adult Great Dane dog. You name him Marmaduke. He is a tannish yellow color. He is sitting on the back seat of your car licking your face. Your parent starts to accelerate the car forward at 2 m/sec/sec to head home.

Calculate the forward force exerted by the seat on Marmaduke. (include unit)

Consider a small frictionless puck perched at the top of a fixed sphere of radius r. if the puck is given a tiny nudge so that it begins to slide down, through what vertical height will it descend before it leaves the surface of the sphere? [hint: use conservation of energy to find the puck's speed as a func e conservation of energy to find the puck's speed as a function of its height at what value of this normal force does the puck leave the sphere? ] here on the puck.
