Two masses, m1 = 20 kg and m2 = 24 kg, are connected by a rope that hangs over a pulley. The pulley is a uniform solid cylinder (I=1/2MR2) of radius R= .3 meter and mass M = 8.0 kilogram. The torque of friction at the axel is τfr = 3.5 Nm. Suppose the rope does not slip.
a.) When the System is released, find the magnitude of the accelerations of the masses m1 and m2.
b.) Find the magnitudes of the velocities of the masses after each of the masses travels a distance d = 1.5 meter?
c.) By that point, determine how much energy is dissipated into heat(due to friction)?
A 1.0-kg block is pushed up a rough 22° inclined plane by a force of 7.0 N acting parallel to the incline. Determine the magnitude of the force of friction acting on the block
An electron microscope operates with electrons of kinetic energy 40keV. What is the wavelength of these electrons? (h= 6.626 x 10^-34 J/s, 1eV= 1.6 x 10^-19 J, and me= 9.1 x 10^-31kg)
If a 100 kilogram person was standing in the elevator and it accelerated downward at 3 m/s^2. What is the force acting on the person feet
A speedboat starts from rest at 2.01m/s2 for 7.00s. At the end of this time, the boat continues for an additional6.00 s with an acceleration of +.518 m/s2. Followingthis, the boat accelerates at -1.49m/s2 for 8.00s.
A spring with spring constant 12.5 hangs from the ceiling. A 400 ball is attached to spring and allowed to come to rest. It is after that pulled down 6.80 and released. What is the time constant if the ball's amplitude has decreased to 3.90 after 57...
