someone help me with questions 3 and 4 please !!
3. A machine part has the shape of a solid uniform sphere of mass 205 g and diameter 4.50 cm. It is spinning about a frictionless axle through its center, but at one point on its equator it is scraping against metal, resulting in a friction force of 0.0200 N at that point. Find its angular acceleration. Let the direction the sphere is spinning be the positive sense of...

A man does 4,650 J of work in the process of pushing his 3.40 times 10^3 kg truck from rest to a speed of v, over a distance of 21.0 m. Neglecting friction between truck and road, determine the following. The speed v m/s the horizontal force exerted on the truck N A 0.42-kg particle has a speed of 2.0 m/s at point A and kinetic energy of 7.5 J at point B. What is its kinetic energy at A?...

a) The 82 kg Bogaraj left the ramp about 45 m lower than his starting position. (That is the difference in elevation was 45m) If you ignore the slowing forces of kinetic friction and wind drag,what was his kinetic energy at that point? b) what was his speed at that point? c) If Bogataj has simply fallen straight down 45 m rather than skiing down a ramp, what would be his kinetic energy? d) After hitting the ground Bogataj crashed...

Sample Problems (Ch.5 Energy) 1A71.4 kg base runner begins his slide into second base when he is moving at a speed of 5-3 m/s. The coefficient of friction between his clothes and Earth is 0.78. He slides so that his speed is zero just as he reaches the base. (a) How much mechanical energy is lost due to friction acting on the runner? (b) How far does he slide? 2.
