A mass m is moving horizontally with a speed of 3.14 m/s just before it strikes a uniform rod of the same mass with length L = 2.12 m, which is initially hanging vertically. The rod is supported by a friction-less axle through a point L/4 down from the upper end of the rod. To what maximum angle (in degrees, with respect to its initial vertical position) will the rod swing before coming back down?

A small object with a mass of 1.62 kg is moving with a speed of 290 m/s (with respect to the ground) when it collides with a rod with a mass of 11.99 kg and a length of L m. The rod is initially at rest, in a vertical position, and pivots about an axis going through its center of mass which is located exactly halfway along the rod. The object imbeds itself in the rod at a distance L/4...

You are designing a slide for a water park. In a sitting position, park guests slide a vertical distance h down the waterslide, which has negligible friction. When they reach the bottom of the slide, they grab a handle at the bottom end of a 6.00-m-long uniform pole. The pole hangs vertically, initially at rest. The upper end of the pole is pivoted about a stationary, frictionless axle. The pole with a person hanging on the end swings up through...

A rod with length L and mass M hangs vertically on a frictionless, horizontal axel passing through its center. A ball of mass m traveling horizontally at speed v0 hits and sticks to the very bottom tip of the rod. To what maximum angle, measured from vertical, does the rod, with the attached ball, rotate? Answer in terms m, M, v0, L, and g.

A thin 1 m long uniform rod with a total mass of 750g is suspended vertically at the upper end. The moment of inertia of the rod in respect to the center of mass is mL*2/12 (where L is the total lenght of the rod). A 9 g bullet is shot to the lower end of the rod and embeds there. The bullet speed before impact is 580 m/s. Calculate the amount of energy transfered to the heat during the...

A bat strikes a 0.145-kg baseball. Just before impact, the ball is traveling horizontally to the right at 49.0 m/s ; when it leaves the bat, the ball is traveling to the left at an angle of 31.0 ∘ above horizontal with a speed of 54.0 m/s . The ball and bat are in contact for 1.61 ms . Find the horizontal and vertical componenets of the average force on the ball

A baseball approaches home plate at a speed of 47.0 m/s, moving horizontally just before being hit by a bat. The batter hits a pop-up such that after hitting the bat, the baseball is moving at 52.0 m/s straight up. The ball has a mass of 145 g and is in contact with the bat for 1.80 ms. What is the average vector force the ball exerts on the bat during their interaction?

A billiard ball moving horizontally, labeled 1, strikes another billiard ball at rest, labeled 2. Before impact, ball 1 was moving at a speed of 2.60 m/s, and after impact it is moving at 0.40 m/s at 55° counterclockwise from the direction of the initial velocity. If the two balls have equal masses of 160 g, what is the velocity of ball 2 after the impact? (Assume ball 1 initially moves along the +x-axis. Enter the magnitude in m/s and...
