A ball initially at rest rolls without slipping down an inclined plane while a block slides without friction down an identical plane. The block and ball both travel the same vertical distance h, before arriving at the bottom.
Which arrives at the bottom with more kinetic energy?
Which arrives at higher linear velocity?

What is the tangential acceleration of a bug on the rim of an 11.00 in.-diameter disk if the disk accelerates uniformly from rest to an angular speed of 79.03 rev/min in 3.60 s? One second after the bug starts from rest, what is its centripetal accel..
Two sinusoidal waves, identical except for phase, travel in the same direction along a string, producing the net wave y(x,t)=(6.0 mm)sin(24.0x -2.0 s-1 * t+0.320 rad), with x in meters and t in seconds. What is the wavelength ? of the two waves? W..
