A yo-yo has a rotational inertia of 1140 g·cm2 and a mass of 81.3 g. Its axle radius is 3.27 mm, and its string is 106 cm long. The yo-yo rolls from rest down to the end of the string.
(a) What is the magnitude of its linear acceleration?
(b) How long does it take to reach the end of the string? As it reaches the end of the string, what are its
(c) linear speed,
(d) translational kinetic energy,
(e) rotational kinetic energy, and
(f) angular speed?
The specific heat capacity of the material use to make the block is C resolve the temperature rise that results from the collision in terms of C and the other given quantities.( suppose that no energy is transferred to the track or the surrounding..
A diver releases an air bubble of volume 2.2 cm3 from the depth of 10 m below the surface of a lake, where the temperature is 7°C. What is the volume of bubble when it reaches just below the surface of the lake, where temperature is 25°C.
Besides the gravitational force, a 3.40-kg object is subjected to one other constant force. The object starts from rest and in 1.20 s experiences a displacement of (5.50 - 3.30) m, where the direction of is the upward vertical direction. find the ..
