Two physicists (on oppisite sides of a cage) are pulling on ropes tied to a lion. Together they must supply a total force = 200 N directed only along the x axis in order to drag the lion straight into the cage. Physicist 1 pulls his rope with a force T1 = 100 N at an angle theta 1 = 60 degree to the axis. What are the force T2 and angle theta 2 of the rope pulled by the physicist 2?
There is a long smooth slope and we release balls from the top of it every 1.5 s. Suppose the acceleration of the ball is 4.8 m/s2 and every ball is numbered in the releasing order.
