4 only please What is the maximum speed that the car can travel at the top of the hill without losing contact withthe ground?Hint: consider the vertical forces on the car at the top of the hill. The sum of forces mustbe equal to its mass times acceleration. At what minimum speed will the normal force of the hill onthe car be zero?4. An archer fires an arrow from a bow. The arrow's mass is 0.082 kg, and an average force of120 N is exerted by the bowstring over a 0.78 m distance. Calculate the velocity of the arrowjust after it is released by the bowstring by two methods:a) Calculate the arrow's acceleration that is caused by the bowstring, and use thekinematic eguations from the first week of class to calculate the velocity at the end ofthe acceleration. Assume a constant acceleration that corresponds to the givenaverage force.b) Use the work-energy theorem to calculate the velocity.5. A truck traveling down the mountain loses its brakes. Fortunately, just ahead is a runawaytruck ramp, which slopes uphil at an angle of 30 degrees from horizontal. The truck has amass of 10,000 kg and is moving at a speed of 100 km/hr just before starting up the ramn
