As the object in the picture moves from point A to point D across the surface, the sum of the gravitational and kinetic energies. A. decreases only B. increases and then decreases. C. decreases and then increases. D. remains the same. The object will have the maximum Kinetic Energy at point___. A B C D The object will have the maximum Potential Energy at point. A B C D If the car has a mass of 1000kg and starts at rest, what is the speed of the car at point C

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 740 n/m. it is initially at rest on an inclined plane that is at an angle of theta= 26 with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is uk = 0.17. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. the block's initial mechanical energy is 9.472 j.b. if the spring pushes the block up the incline, what distance l in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
