You are driving along a road at  28m/s. Suddenly a child on a bike appears 60m ahead of you. You slam  on the brakes and decelerate at  7m/s2. Do you hit the child on the bike?

Two cars are heading towards one another. Car A is moving with an acceleration of aA = 7 m/s2. Car B is moving with an acceleration of aB = -4 m/s2. The cars are initially at rest and separated by a distance d = 2300 m on the x-axis. At what time, in seconds, do the cars meet? What is the displacement, in meters, of Car A? What is the displacement, in meters, of Car B? Now assume that both cars start with an initial velocity. Car A's initial velocity is v0A = 23 m/s and Car B's initial velocity is vB = -17 m/s. At what time, t2 in seconds, do they meet?

An electron is moving in a straight line with a initial speed of3E5 m/s. It then undergoes an accelerates 8E14m/ s. How long will it take to reach a speed of 5.4E 5m/s?

4. You wake up in a strange room, with opaque walls, and no visible doors or windows. you drop a ball from a height of 1.12 m and it hits the floor 0.191 s after you drop it. This time you suspect you are on a rocket that has just left the surface of the Earth, and is still not too far above the ground. What do you deduce the rocket s acceleration to be?     71.2 m/s^2     61.4 m/s^2     98.0 m/s^2     51.6 m/s^2

You are driving down the highway late one night at 20 m/s when a deer steps onto the road 35 m in front of you. Your reaction time before stepping on the brakes is 0.50 s, and the maximum deceleration of your car is 10 m/s?. How much distance is between you and the deer when you come to a stop?

A police car gets passed by a car traveling at a constant speed of 150.0 km/hr.  The police car accelerates from rest at 5.00 m/s2, the moment the two cars are side by side.  How long does it take the police officer to catch the car?

A billiard ball was set in motion on a counter by your mischievous little cousin who wanted the ball to hit your foot. To avoid your attention he set the ball in motion with a slow speed of 1.0 m/s (how did he know this unit?!) from a counter that is 1.1 m tall. Fortunately he missed. How long did it take to hit the floor?
