You are sitting in your car at a red light when you see a zombie standing still 65m in front of your car. You both begin to accelerate towards each other. Your car accelerates at 1.8 m/s^2 and the zombie accelerates at 0.6 m/s^2. How long does it take for you to strike the zombie? Make sure to include a diagram of the physical situation, label known and unknown quantities with units, and coordinate system. Thanks!

Bob has just finished climbing a sheer cliff above a beach, and wants to figure out how high he climbed. All he has to use, however, is a baseball, a stopwatch, and a friend on the beach below with a long measuring tape. Bob is a pitcher and he knows that the fastest he can throw the ball is about vo = 34.5 m/s. Bob starts the stopwatch as he throws the ball (with no way to measure the ball's initial trajectory), and watches carefully. The ball rises and then falls, and after t₁ = 0.510 s the ball is once again level with Bob. Bob cannot see well enough to time when the ball hits the ground. Bob's friend then measures that the ball landed x = 128 m from the base of the cliff. How high up is Bob, if the ball started exactly 2 m above the edge of the cliff? 2 m -- X Bob's position= x10 TOOLS m
