Question

1. A basketball leaves a player's hands at a height of 2.20 m above the floor. The basket is 3.05 mabove the floor. The player likes to shoot the ball at a 38.0 angle.   If the shot is made from a horizontal distance of 6.80 m and must be accurate to ±0.23m (horizontally), what is the range of initial speeds allowed to make the basket?

2. An airplane is traveling 835 km/h in a direction 41.5 west of north ? How far north and how far west has the plane traveled after 2.00 h ?

3. Suppose a vector V  makes an angle with respect to the y axis.

What could be the x and y components of the vector V ?

Explanation / Answer

2.

North component = 835 cos 41.5 = 625.37 km/hr

and

West component = 835 sin 41.5 = 553.28 km/hr

Plane would travel after 2 hours 625.37*2 = 1250.74 km towards north

553.28*2 = 1106.56 km towards west
