The image above shows musical genius Prince, or "the artist formerly known as Prince," driving his little red corvette on a hilly countryside road. During our observation the 1,?9410 kilogram car goes over a 5.35 meter-radius-hill and then down into a 14.2 meter-radius-valley as shown. When our observation begins the little red corvette is near the top of hill A and its kinetic energy is 3.5?X10M Joules. Once it begins its descent into valley B it begins to speed up and gains another 1.?QX1OA4 Joules of kinetic energy by the time it is at the bottom of the dip. 1.) What is the vehicle's speed at the top of hill A ? 2.) What is the magnitude of the vehicle's radial acceleration when it is at the top of hill A '? 3.) What is the magnitude of the normal force on the vehicle when it is at the top of hill A ? 4.) What is the vehicle's speed at the bottom of dip B ? 5.) What is the magnitude of the vehicle's radial acceleration when it is at the bottom of dip B '? 6.) What is the magnitude of the normal force on the vehicle when it is at the bottom of dip B 7 7.) What is the maximum kinetic energy that the vehicle can have at the top of hill A in order to remain in contact with the road
