Question

A uniform disc of mass m =12 kg slides down along smooth, frictionless hill,
released from the rest at a height of h = 1.25 m (it has no initial speed and it
=6kg, which can move on a frictionless surface. The coefficient of kinetic frict
length of the cart (in m) so that the disc begins to roll without slipping before la
M
smooth
O 714​

Answer 1

Explanation:

is 156 is a common multiple of 3 and 13?

Answer 2

Answer:

7/8

Explanation

when rolling  = Vp=Va

Vo-μgt-(αtr)=(μmg/M)t

Vo=3μgt+μmg/M*t

l=7/8
