A child of mass 49.1 kg sits on the edge of a merry-go-round with radius 2.6 m and moment of inertia 262.214 kg m2 . The merrygo-round rotates with an angular velocity of 2.5 rad/s. What radial force does the child have to exert to stay on the merry-go-round? Answer in units of N.

Ineed extreme for task 2. my student number is 571721. many to whoever solves this correctly, im in debt to you.

Free runners jump long distances and land on the ground or a wall. how do they apply newton’s second law to lessen the force of impact?

An charge with mass m and charge q is emitted from the origin, (x, y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.
