Calculate the tension in a horizontal string that whirls a 1.6-kg {rm kg} toy in a circle of radius 2.0m m when it moves at 3.0m/s m/s on an icy surface
A 2.50m -long, 500g rope pulls a 7.00kg block of ice across a horizontal, frictionless surface. The block accelerates at 2.30m/s2 . How much force pulls forward on (a) the ice, (b) the rope?
