A cylinder is rolling along the ground without the slipping, Ask an Expert

Academics

Q. A cylinder is rolling along the ground without the slipping at 7m/s. It comes to a hill and begins going up. Assume no losses to friction, how high vertically would it go before it stops?

Q. A 3.83kg object is swung in a vertical circular path on a string 6.19 m long. The acceleration of gravity is 9.8m/s^2. If the speed at the top of the circle is 8.4 m/s, what is the tension in the string when the object is at the top of the circle? Reply in units of N.
