An average person can reach a maximum height of about 60 {\rm cm} when jumping straight upfrom a crouched position. during the jump itself, the person's bodyfrom the knees up typically rises a distance of around 50 {\rm cm}. to keep the calculationssimple and yet get a reasonable result, assume that the entirebody rises this much during the jump. in terms of this jumper's weight w , what force does the ground exert on him or herduring the jump?

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.
