What is the speed of the bead at point C?
Here are the details...Point A is 100cm above the potential energy line, B is on the potential energy line and C is 80cm is above the potential energy line. (It's on a graph) Thats all the information it gave me. Can you please show me how to do it.
Thank you.

A car accelerates from rest to a speed of 18.0m/s in 6.00 seconds. If the car weighs 16,0000N, what average power must the motor produce to cause this acceleration?

Can you please show me how to do this.
Thanks.

A bullet is fired form ground level with a speed of 75.0m/s at an angle of 30.0 degrees above the horizontal at a location where g=10m/s^2. What is the horizontal component of its velocity when it is at the highest point of its trajectory?

Can you please show me how to do this.

When a large star becomes a supernova, its core, with a mass about equal to that of our sun, may be compressed so tightly that it becomes a neutron star (composed of only neutrons). Suppose the radius of the neutron star is 20 km (about the size of Rochester) and that it rotates once every 1.2 s.

(a) What is the speed of a neutron on the surface of the neutron star at its equator? m/s

(b) What is the magnitude of the acceleration of this neutron? m/s2
