- An athlete wants to run a 1500m race with an average velocity of 6.00 m/s. After running the first 500m, he notices that the time elapsed is 100 seconds. Panicking, he accelerates for “t” seconds at 0.2 m/seconds^2 and finishes the race at his new faster speed. He makes it just in time. How long did he accelerate for? (Use 5 significant figures in the answer)#1Q1) There are two cars. Car A moves at a constant velocity Va m/s. Car B moves at a constant velocity Vb m/s. They both move along the same straight path called the x-axis. When a timer starts to click (t = 0), they are L meters (m) apart with Car A at x = 0 and Car B at x = L m. (a) Derive a formula for the time Tmeet at which Car A and Car B meet in terms of the given symbols Va, Vb and L. Hence, obtain a formula for the location Xmeet at which the cars meet. Given that Car A moves at a constant speed of 18 m/s (which is about 65 km per hour). Car B moves at a constant speed of 12.5 m/s (which is 45 km per hour). They both move along the same straight path called the x-axis. When a timer starts to click, they are 1000 m apart with Car A at x = 0 and Car B at x = 1000 m. (b) Car A and Car B are both moving in the positive x direction. Apply your results in (a) to find the time and the position at which they meet. (c) Here is a twist. Car A moves in the positive x direction and Car…

- 1) A race car travels around a circular race track for which the start line and finish line are at the same location. If the race is 888km long and the radius of the track is 1.414km, how many times did the car go around the track? The race takes 2 hours and 45 minutes, what is the race car’s average velocity (in m/s) over the entire race? What is the race car’s average speed (in m/s) over the entire race?Problem 2: Kinematics and vectors.
