Question 3 1 pts
Two students are doing The Cart and the Brick Lab. The cart has a mass of 8.8 kg cart
and is initially moving at 7.2 m/s. A brick of mass 5.6 kg is then dropped on top of the
cart and the two roll away together. Calculate the final velocity of the brick and cart, and
then round your answer to the tenths place.

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.
