Q1 starting from rest an13 kg block slides133 m down a, Ask an Expert

Academics

Q1. Starting from rest, a(n)13 kg block slides13.3 m down a frictionless ramp (inclined at 30? from the ?oor) to the bottom. The block then slides an additional 26.3 m along the ?oor before coming to stop.

The acceleration of gravity is 9.8 m/s.

Find speed of the block at the bottom of the ramp.

Answer in units of m/s

Q2. What is tangential acceleration of a bug on the rim of a 78 rpm record of diameter 7.41 in. if the record moves from rest to its final angular speed in 4 s? The conversion between inches and meters is 0.0254 m/in.

Answer in units of m/s2
