Do the same for the velocity vs. time graphs in the x and y directions. Compare (position vs. time) and (velocity vs time) How can you determine the values of the constants of these functions for the functions for position vs time and for velocity vs time? What Kinematics quantities do these constants represent?
An object is launched at 19.6 meters per second (m/s) from a 220.5-meter tall platform. The function that represents the object's height s at time t seconds after launch is s(t) = −4.9t2 + 19.6t + 220.5, where s is in meters. When does the object strike the ground?
You are walking to your physics class at speed 1.0m/s with respect to the ground. Your friend leaves 2.0 min after you and is walking at speed 1.3m/s in the same direction. How fast is she walking with respect to you? How far does your friend travel before she catches up with you? Indicate the uncertainty in your answers. Describe any assumptions that you made.
A spaceship ferrying workers to Moon Base I takes a straight-line path from the earth to the moon, a distance of 384,000 km. Suppose it accelerates at an acceleration 20.4 m/s2m/s2 for the first time interval 15.5 minmin of the trip, then travels at constant speed until the last time interval 15.5 minmin , when it accelerates at −− 20.4 m/s2m/s2 , just coming to rest as it reaches the moon. A) What is the maximum speed attained? B) What fraction of the total distance is traveled at constant speed? C) What total time is required for the trip?

Miles wants to chase a truck that is going at a speed of 25.0 kph, and thus starts accelerating from rest at 4.00 m/s. Caesar, sensing that Miles wants to steal property, and seeing him when he is 100.0 m away from him, rides a police car and starts accelerating at 10.0 m/s. Once Caesar’s car catches Miles, what is the distance traveled by the truck since Caesar started chasing Miles?
