1. A 25 kg child runs at a speed of 5.0 m/s and jumps
onto a stationary shopping cart and holds on for dear life. The
cart has mass 12 kg. Assuming the child rides on the cart after the
collision, find the speed of the child and shopping cart just after
the child jumps on. Show all work please

A child runs and jumps into an)initially stationary) playground swing. The child is moving in 5.0 m/s just before landing in the seat of the swing. Her mass is 20 kg, the swing seat has mass 5.0 kg, and the ropes holding it have negligible mass. How high does the swing rise from its initial position? 8.0 m 1.0 m 1.3 m 1.7 m 0.82 m A spring is compressed from its relaxed position by an amount of 0.20 m....

An 85.0 kg child runs in a straight line towards the edge of a stationary merry-go-round at 2.50 m/s. The merry-go-round is in the shape of a disk and has a diameter of 4.50 m and a mass of 235 kg. The child jumps onto and stays on the merry-go- round. What is the angular momentum of the child before this collision, in kg m2/s? (A) What is the moment of inertia of the merry-go-round, in kg m27 [B) What...

A 40.0-kg child running at 3.00 m/s suddenly jumps onto a stationary playground merry-go-round at a distance 1.50 m from the axis of rotation of the merry-go-round. The child is traveling tangential to the edge of the merry-go-round just before jumping on. The moment of inertia about its axis of rotation is 600 kg ? m2 and very little friction at its rotation axis. What is the angular speed of the merry-go-round just after the child has jumped onto it?...

A 36.0 kg child runs with a speed of 2.80 m/s tangential to the rim of a stationary merry-go-round(Figure 1) . The merry-go-round has a moment of inertia of 518 kg⋅m2 and a radius of 2.31 m . When the child jumps onto the merry-go-round, the entire system begins to rotate. Calculate the final kinetic energy of the system.

A 46.7 kg student runs down the sidewalk and jumps with a horizontal speed of 4.10 m/s onto a stationary skateboard. The student and skateboard move down the sidewalk with a speed of 3.86 m/s. a) Find the mass of the skateboard. Answer in units of kg b) How fast would the student have to jump to have a final speed of 6.54 m/s? Answer in units of m/s..

A 25-kg child running at 1.6 m/s jumps onto the outer edge of a merry-go-round of 200-kg mass and 1.8 m radius. If the merry-go-round starts from rest, what is the final angular velocity in rad/s of the child and merry-go-round? Use conservation of angular momentum and treat the merry-go-round as a solid disk.
