Homework Statement http://serv1.gulfup.cc/i/00003/ev7u8r04c18k.jpg Homework Equations K1+U1=K2+U2 The Attempt at a Solution I have the solution i am just confused about one point, in the solution, it considred both the translational and rotational kinetic energy for the cylinder on the...

al alright, thanks for putting up with me :)

sorry about that my mistake, but should i subtract then? that did not give me a correct answer either. in my calculation the answer is equal to the centripetal force only, so it doesn't matter where on the trak the object is, it will be the same answer?

I am adding because at the lowest point the gravitational and centripetal forces are in the same direction, therefore the resultant will be the addition of the two.

"What is the magnitude of the resultant force on the 60-kg driver" it asked about the force exerted on the driver, so by Newton's third law, the magnitude of the force exerted on the driver is equal to the magnitude of the force the driver exerts on the track (action reaction pair) which in this...

Homework Statement A car travels along the perimeter of a vertical circle (radius = 0.25 km) at a constant speed of 30 m/s. What is the magnitude of the resultant force on the 60-kg driver of the car at the lowest point on this circular path? Question options: 1) 0.37 kN 2) 0.80 kN 3) 0.22 kN...
