Question

A ball is thrown at speed v from zero height on level ground. At what angle should it be thrown so that the area under the trajectory is maximum? A block of mass m1. hanging off an inclined plane with angle of inclination (theta), is attached by a massless cord and frictionless pulley to a second block of mass m2 resting on the same inclined plane. Mass m2 rests on a horizontal surface with coefficient of static friction, u. Calculate the critical ratios k1 and k2: for m1/m2 > k1. ml will accelerate downward, and pull m2 up the inclined plane while doing so. tor m1/m2

Explanation / Answer

Problem 5.

A = 0 to R ydx
where y = xtan - gx^2/2u^2/cos^2

Putting dA/d = 0.

we get = 60 deg
