How do we calculate banking angle of a ramp which has a radius r1 if a car has to travel at a velocity of v1 without losing control. The ramp is an increasing radius ramp with inner most radius at r1 and outermost radius at r2. What would the banking angle be at inner most radius r1 and outer most radius r2 if the car has an entry velocity of v1 and an exit velocity of v2.
A quarterback claims that he can throw the football a horizontaldistance of 196.6 m (215 yd). Furthermore,he claims that he can do this by launching the ball at therelatively low angle of 25° above the horizontal. To evaluate his claim, determine ..
