(a) What is the ratio of the speed of the raindrops to the speed of the bus? (b) Find the speed of the raindrops, given that the bus is moving with a speed of 18 m/s.

A stone is thrown at a cliff with a height of h. If the stone is thrown with an initial speed of 42 m/s at an angle θ=60° and hits the cliff at A 5.5 seconds later, determine the speed of the stone when it hits A. Use g = 10 m/s/s.
The initial velocity of a car, v i is 45 km/hr in the positive x-direction. The final velocity of the car, vf is 66 km/hr in a direction that points 750 above the positive x-axis. Sketch the vectors v = v f − v i . Find the magnitude of the change in velocity v. Find the direction of the change in velocity v.
A few seconds after a plane took off it was hit by a missile launched from a distance on the
ground. The path of the plane is described by y= (0.0005 x²) m. The missile traveled along
a parabolic path described by y = (160 x), where the coordinates are measured in meters.
If the components of the missile velocity in the horizontal and vertical directions are
constant at v; =120 m/s and v, = 100 m/s, respectively, and the plane was rising with a
constant upward velocity v, = 12 m/s, determine the magnitudes of the velocity and
acceleration of the plane the moment it was hit by the missile.
