Starting from rest, a(n)9 kg block slides 9.7 m

down a frictionless ramp (inclined at 30◦

from

the ﬂoor) to the bottom. The block then

slides an additional 23.5 m along the ﬂoor

before coming to stop.

The acceleration of gravity is 9.8 m/s

2.Find the speed of the block at the bottom

of the ramp.

Answer in units of m/s
