A soccer ball is kicked from the ground at an angle of θ = 54 degrees with respect to the horizontal. The ball is in the air for a time tm = 2.4 s before it lands back on the ground.

Acar of mass m goes around a banked curve of radius r with speed v. if the road is frictionless due to ice, the car can still negotiate the curve if the horizontal component of the normal force on the car from the road is equal in magnitude to 101) a) mv2/r b) mg/2. d) mg e) tan[v2/(eg)]
