Page 13 9. A 49.8-kg athlete running at 4.54 m/s suddenly jumps onto a stationary playground merry-go-round at a distance 1.45 m from the axis of rotation of the merry-go-round. She 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 625 kg m2 and very little friction at its rotation axis. What is the angular speed of the merry-go-round just after she has jumped onto it?...

My Notes + Ask Your Teacher John is pushing his daughter Rachel in a wheelbarrow when it is stopped by a brick 8.00 cm high (see the figure below). The handles make an angle of a = 20.0° with the ground. Due to the weight of Rachel and the wheelbarrow, a downward force of 405 N is exerted at the center of the wheel, which has a radius of 15.0 cm....

please help!
The figure below shows a metal ball with a mass of 2.84 kg bouncing off a wall. The ball has the same speed just before and just after the impact (v - 10.0 ms, and the angle its path makes with the wall is 8 - 60.0° as shown. (Because we are analyzing the motion of the ball over a very short time just before and after Impact, you may safely ignore the effect of gravity on the...

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A student stretches a spring, attaches a 1.90 kg mass to it, and releases the mass from rest on a frictionless surface. The resulting oscillation has a period of 0.650 s and an amplitude of 30.0 cm. Determine the oscillation frequency, the spring constant, and the speed of the mass when it is halfway to the equilibrium position. HINT (a) the oscillation frequency (in Hz)...

1- A block slides along a frictionless surface at 2.4 m/s. A second 3.5-kg block, sliding at a faster 7.5 m/s, collides with the first from behind and sticks to it. The final velocity of the combined blocks is 4.6 m/s. What was the mass of the first block? 2-A 15 g ball of clay traveling west at 4 m/s collides with a 50 g ball of clay traveling 30° north of east at 3.5 m/s. What is the speed...
