Answer the following questions
Remember:
position is equal to the velocity multiplied by time plus the initial position (x = v*t + xi)
velocity is equal to the displacement divided by time
(v = x/t)
1) A person riding their bike on a nice cloudy day travels 50 meters in 20 seconds. How fast are they moving?
2) A car going down the road has a velocity of 20 m/s. If the car continues at this rate for 7 seconds how far did the car go?
3) A professional baseball player can throw the ball around 45 m/s if the distance between the pitcher and the batter is 18.39 m. How much time does it take for the ball to get to the batter?
4) The average NASCAR drive is moving at around 100 m/s. If the NASCAR track is roughly 850 m. How long does it take the NASCAR drivers to make a lap?

One hazard of space travel is debris left by previous missions. there are several thousand masses large enough to detect by radar orbiting the earth, but there are far greater numbers of very small masses such as flakes of paint. calculate the force exerted by a 0.110 mg chip of paint that strikes a space shuttle window at a relative speed of 5.00 ✕ 103 m/s and sticks, given the collision lasts 6.00 ✕ 10-8 s. such a collision chipped the window of the ill-fated challenger in june 1983, causing $50,000 of damage.
