Questions
A cylinder of mass 4 m and a block of mass m is placed on an inclined plane as shown in the figure. The linear acceleration of cylinder is
a
2m/s2
b
4m/s2
c
107m/s2
d
37m/s2
detailed solution
Correct option is B
The velocity of the block and the velocity of the top point of the cylinder same i.e., doble the velocity of center of mass, from conservation of energy.mgh=12 mυ2+124mυ22 1+k2R2mgh=12 mυ2+124mυ22 1+12=12 mυ2+12mυ232=12 mυ21+32mgh=12 mυ2524gh5=υ2 υ2=2ah2a=4g5a=2g5=4m/s2Talk to our academic expert!
