Alarge wedge with a mass of 10kg rests on a horizontal frictionless surface, as shown. a block with a mass of 5.0kg starts from rest and slides down the inclined surface of the wedge, which is rough. at one instant the vertical component of the block’s velocity is 3.0m/s and the horizontal component is 6.0m/s. at that instant the velocity of the wedge is:

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.

At what time would the magnitude of the velocity reach 36.00 km/hr
