To solve this problem it is necessary to apply the expressions related to the calculation of angular acceleration in cylinders as well as the calculation of linear acceleration in these bodies.
By definition we know that the angular acceleration in a cylinder is given by

Where,
= Coefficient of kinetic friction
g = Gravitational acceleration
r= Radius
= Angle of inclination
While the tangential or linear acceleration is given by,

ANGULAR ACCELERATION, replacing the values that we have



LINEAR ACCELERATION, replacing the values that we have,


Therefore the linear acceleration of the solid cylinder is
Answer:
+ 5 m/s
Explanation:
change in displacement = ΔX=final position - initial position
ΔX = 0-(-5) =0+5 =+ 5 m
average velocity = ΔX/t
= +5/1
= + 5 m/s
positive sign shows that ball rolls towards right
Answer:
Explanation:
where W-weight, m-mass of the object and g-acceleration produced due to the earth's gravity. ... This happens because the normal reaction force exerted on the object in the lift is equal to zero, and normal force equals to mg, which in turn equals the weight of the object.
60 Miles per hour 60 times 2 is 120
