2) A massless string across a massless, frictionless pulley connects block of mass 5.35 kg, to block B, of mass 4.27 kg. Block A lies on a smooth ce and block B hangs straight down from the pulley. Block B falls and block A moves across the horizontal surface. Find a) the acceleration of the blocks and b) the tension in the string.
Three crates with various contents are being pulled by a 3575-N
force across a horizontal, frictionless roller-conveyor system. The
group of boxes is accelerating on the conveyor at 1.578 m/s2 to the
right. Between each adjacent pair of boxes is a force meter that
measures the magnitude of the tension in the connecting rope.
Assume that the ropes and force meters are massless.
A 50.0-kg crate is being pulled along a horizontal, smooth surface The pulling force is 10.0 N and is directed 20.0" above the horizontal What is the acceleration of the crate? An object of mass 25 kg, attached to an ideal massless spring, is pulled across a frictionless surface. If the spring constant is 100 N/m and the spring is stretched by 0.5 m, calculate the acceleration of the object when released.
