Two objects (18.0 and 52.0 kilogram) are connected by a mass less string that passes over a mass less, frictionless pulley. The pulley hangs from the ceiling.
(a) Evaluate what is the acceleration of the objects?
(b) Evaluate what the tension in the string.
The speed of a bullet as it travels down the barrel of a gun isgiven by V=-5000t2 -300t, where v is in km/s and tin seconds. The acceleration of the bullet as it leaves the barrel is zero.
