Question

A solid cylinder of mass 2 kg and radius 50 cm rolls
up an inclined plane of angle inclination 30°. The
centre of mass of cylinder has speed of 4 m/s. The
distance travelled by the cylinder on the incline
surface will be : (Take g = 10 m/s2)
(1) 2.2 m
(2) 1.6 m
(3) 1.2 m
(4) 2.4 m​

Answer 1

Answer:

opt 4( 2.4m)

Explanation:

mgh = 1/2mv^2 + 1/4 mr^2omega^2

s = 3/4 v^2/gsin teta

= 12/5

=2.4m
