Question

Physics

A ball of mass m1 =5.2 kg and a block of mass m2 =2.0 kg areconnected with a lightweight string over a pulley with moment ofinertia I and radius R=0.25m. The coefficient of kinetic frictionbetween the table top and the block of mass m2 is μk = 0.4. If themagnitude of the acceleration is a=2.7 m/s2.
torque_rotational
a)What are the tensions T1 and T2 in the string.
T1=
N

T2=
N
b)Calculate the moment of inertia of the pulley.

I=
kg m2
c) What is the change of the kinetic energy of the system if thesystem is released from rest and the ball decends a distance h=7.9m downward.

ΔK =
