Two trains a and b of length 400 m each are moving on two parallel tracks with
uniform speed of 72 km/h in the same direction with a ahead of b. the driver of b
decides to overtake a and accelerates by 1 ms-2. if after 50 s, the guard of b just
brushes past the driver of a, what was the original distance between the trains.

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.
