A motorcycle is following a car that is traveling at constant speed on a straight highway. Initially, the car and the motorcycle are both traveling at the same speed of 20.5 m/s , and the distance between them is 60.0 m . After t1= 4.00, he motorcycle starts to accelerate at a rate of 4.00 m/s^2. The motorcycle catches up with the car at some time t2. 1) How long does it take from the moment when the motorcycle starts to accelerate until it catches up with the car? In other words, find t2−t1. 2)How far does the motorcycle travel from the moment it starts to accelerate (at time t1) until it catches up with the car (at time t2)? Should you need to use an answer from a previous part, make sure you use the unrounded value.
A toy remote-control car starts from rest, reaches the velocity v1=1.15 m/s by the moment t1=3.1 s and than keeps this velocity by the moment of time t2=13.6 s. What distance from its initial position does the car travel by the moment t2? Assume that the car moves along a straight line.
In Example 2.12, two circus performers rehearse a trick in which a ball and a dart collide. Horatio stands on a platform 7.8 m above the ground and drops a ball straight down. At the same moment, Amelia uses a spring-loaded device on the ground to launch a dart straight up toward the ball. The dart is launched at 16.0 m/s. Find the time and height of the collision by simultaneously solving the equations for the ball and the dart. time:?s height:?m

Archibald, an aging geezer, is out bicycling one fine afternoon, reliving his glorious youth and oblivious to the world around him. As he approaches a busy intersection, a police officer directing traffic blows his whistle to get Archie’s attention so he’ll slow down and stop. But Archie doesn’t stop; he just speeds right through the intersection as if the traffic cop wasn’t even there. The cop radios one of his colleagues and gets her to stop the old geezer. She gives him a traffic citation for failing to heed the command of a police officer directing traffic. When the case gets to traffic court, Archie explains to the judge that he didn’t hear the officer’s whistle because he is going deaf and cannot hear frequencies above 3000 Hz. The traffic cop informs the judge that his standard issue police whistle emits a frequency of 2100 Hz and he has a certificate to prove it. Thinking quickly (at least for an old geezer) Archie says that it may be true that the police whistle emits a sound…
