Your school science club has devised a special event for homecoming. you've attached a rocket to the rear of a small car that has been decorated in the blue-and-gold school colors. the rocket provides a constant acceleration for 9.0s. as the rocket shuts off, a parachute opens and slows the car at a rate of 5.0m/s2. the car passes the judges' box in the center of the grandstand, 990m from the starting line, exactly 12s after you fire the rocket.

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 790 n/m. it is initially at rest on an inclined plane that is at an angle of 28 degrees with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is k = 0.14. in the initial position, where the spring is compressed by a distance of a = 0.18 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. 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.
