# 4. An unmarked police car traveling a constant 95 km/h is passed by a speeder traveling 135 km/h. Precisely 1.00 s after the speeder passes, the police officer steps on the accelerator; if the police car's acceleration is 2.00 m/s2, how much time passes before the police car overtakes the speeder (assumed moving at constant speed)? #5. A baseball is hit almost straight up into the air with a speed of about 20 m/s. (a) How high does it go? (b) How long is it in the air?

Question

Please help me answer number 5 with complete solution

#2. Draw each of the following vectors, then express these vectors in terms of unit vectors. a) d = (100 m, 45° below +x axis) b) i = (300 m/s, 20° above +x axis) c) a = (5,-y axis) m s2 # 3. A car slows down uniformly from a speed of 18.0 m/s to rest in 5.00 s. How far did it travel in that time? Make an x vs t, v vs t, and a vs t graphs of the motion of the car. # 4.
