A10 g toy car moving to the right at 20 cm/s has a head-on nearly elastic collision with a 24 g toy car moving in the opposite direction at 35 cm/s. after colliding, the 10 g car moves with a velocity of 58 cm/s to the left. find the speed of the second car after the collision. answer in units of cm/s.

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.
