Question: You're driving down a country road at 25 m/s, when a deer suddenly starts crossing the road. As soon as you react, you hit the brakes to decelerate the car at a rate of 4.20 m/s2. If the deer is 77 m ahead of you, do you hit the deer with your car?

Driving down a quiet street on a summer day with the car windows down, you see a convertible approaching from the opposite direction, with the driver playing her car stereo loudly. Having a well-trained musician’s ear, you notice that the song you hear is in a key one semitone (the interval between two adjacent keys on a piano) above the key in which the song is typically heard. You also know that to shift any note by one semitone, the...

A child rides down the road on his bike at a speed 4.3 m/s with a balloon tied to its handle bars. At a time t = 0 s, the balloon comes untied and floats into the air. It accelerates with the vector: a(t) = ( -0.31 m/s2 e(-0.072093 s-1 t ) , 4.71 m/s2 - 0 m/s3 t ) [Note: The acceleration coefficient in the x-direction should be v0? (= -0.3099 m/s2) where v0 is the initial speed and...

A car is going at 11.2 m/s on a horizontal straight road. When the traffic light is 30 m away, it turns red. The reaction time of the driver is 0.3 s. The car stops just before the traffic light with constant deceleration when the break is applied. Find the time it takes for the car to stop, from the moment the light becomes red. Plot speed of the car on y-axis and the time on the x-axis, taking t=0...
