In heavy rush-hour traffic, you drive in a straight line at 12 m/s for 1.5 minutes, then you have to stop for 3.5 minutes, and finally, you drive at 15 m/s for another 2.5 minutes. Plot a position-versus-time graph for this motion. Your plot should extend from t = 0 minutes to t = 7.5 minutes. Assume x=0 and t=0 at the start of your motion.

The figure shows an acceleration- time graph of a particle with a starting velocity at 60 m/s and the distance travelled is 200 meters at 10 seconds. Draw the (v-t), and (s-t) graphs of the particle. Determine the total distance travelled and its velocity at 18 seconds. 4m/s? 10s te14s t= 18s Am/s

A car starts from rest. It accelerates at constant acceleration for 5.0 seconds during which the car covers a distance of 125 m. After that the car continues at that speed for 22 seconds, after which the car slows down at a constant deceleration of – 4.5 m/sec2 until coming to a complete stop. Draw a v vs t, graph, label all the relevant data, and use the graphical method to determine total distance traveled.

A car has an initial velocity of 17.8 m/s (SOUTH). The car has an unknown acceleration for a time of 7.11 seconds, at which point the car has a final velocity of 4.20 m/s (NORTH). During this time what is the car's displacement?

Ilya and Anya each can run at a speed of 7.60 mph and walk at a speed of 3.50 mph . They set off together on a route of length 5.00 miles . Anya walks half of the distance and runs the other half, while Ilya walks half of the time and runs the other half. a) Find Anya's average speed. b) How long does it take Ilya to cover the distance? (in minutes) c) Now find Ilya's average speed. Thanks

A car accelerates at a constant rate from rest to 16 m/s in a distance of 74 m. What is the magnitude of its acceleration, in m/s2? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

Cheetahs can accelerate to a speed of 20.0m/s in 2.50 s and can continue to accelerate to reach a top speed of 27.8 m/s. Assume the acceleration is constant until the top speed is reached and is zero thereafter. Let the +x-direction point in the direction the cheetah runs.  Express the cheetah's top speed vtop in miles per hour (mi/h). Vtop= ______________ mi/h Starting from a crouched position, how much time taccel does it take a cheetah to reach its top speed, what distance d does it travel in that time?  taccel = ____________ s d=_____________ m If a cheetah sees a rabbit 129.0 m away, how much time ttotal will it take to reach the rabbit, assuming the rabbit does not move and the cheetah starts from rest?  ttotal = _________ s

The speed of an object as a function of time is given by the following equation: What is the magnitude of the object's acceleration (in m/s2) at t = 5 s? X 32

A rocket-powered sled moves along a track, eventually reaching a top speed of 261 m/s to the west. It then begins to slow down, reaching a complete stop after slowing down for 3.37 s. What was the sled s average acceleration and velocity during the slowdown phase?
