13–38. The 300-kg bar B, originally at rest, is being towed over a series of small rollers. Determine the force in the cable when t = 5 s, if the motor M is drawing in the cable for a short time at a rate of v = (0.4r²) m/s, where t is in seconds (0 = 1s 6 s). How far does the bar move in 5 s? Neglect the mass of the cable, pulley, and the rollers.

There are 2 thin uniform rods. Rod DC is pinned at its center of gravity (free to rotate 360 degrees), 6 FT long, and perfectly horizontal. Rod AB is perfectly vertical, pinned at the bottom of the rod and 6 FT long as well. Both pins are on the ground (So they form a perfectly horizontal line if you connect them). The pines are 9 FT away from each other. Rod AB is released from rest and hits the end of DC with a coefficient of restitution of 0.6 . DETERMINE THE ANGULAR VELOCITY OF BOTH RODS JUST AFTER IMPACT ASSUMING BOTH WEIGH 20 LBS EACH.
A spring with spring constant k and equilibrium length zero is attached tothe top of a frictionless hoop of radius R. The spring is stretched and connected to a bead of mass m at the bottom of the hoop. At t = 0 the bead is given an initial speed v0 and the bead moves up the hoop. Find the speed of the bead as a function of position on hoop v(θ).
A mass m = 77 kg slides on a frictionless track that has a drop, followed by a loop-the-loop with radius R = 19.9 m and finally a flat straight section at the same height as the center of the loop (19.9 m off the ground). Since the mass would not make it around the loop if released from the height of the top of the loop (do you know why?) it must be released above the top of the loop-the-loop height. (Assume the mass never leaves the smooth track at any point on its path.) ) What is the minimum speed the block must have at the top of the loop to make it around the loop-the-loop without leaving the track? m/s What height above the ground must the mass begin to make it around the loop-the-loop? m If the mass has just enough speed to make it around the loop without leaving the track, what will its speed be at the bottom of the loop? m/s If the mass has just enough speed to make it around the loop without leaving the track, what is its speed at the…

A small child of mass m = 38 kg is swinging on a swing. The length from the upper bar of the swing set to the seat is L = 4.4 m. The kid is attempting to swing all the way around in a full circle. Assuming the kid is traveling at the speed found in part (a), what is their apparent weight, Wa in newtons, at the top of their path? (At the top, the kid is upside-down.)
