A Porsche challenges a Honda to a 500m race. Because the Porsche's acceleration of 3.5 m/s^2 is larger than the Honda's 3.0 m/s^2, the Honda gets a 1.0 s head start. A. Who wins? Porsche wins B. By how many seconds?

A jet plane lands with a speed of 145 m/s and can accelerate at a maximum rate of -7.00 m/?2 as it comes to rest. a. From the instant the plane touches the runway, what is the minimum time interval needed before it can come to rest? b. Can this plane land on a small tropical island airport where the runway is 0.9 km long? Why?

Anna and Bridget live 33 km apart. They cycle to meet each other. Anna travels at 10 km/h and Bridget travels at 12 km/h. a  How long until they meet each other? b  What distance have they each travelled?

a. Find the velocity v(t) and acceleration a(t). b. At what value of t does v=0? c. What is the maximum height?

2. A jet plane has a takeoff speed of vtakeoff = 73 m/s and can move along the runway at an average acceleration of 2.4 m/s2. The runway is 1.2 km. Write out the 3 Kinetic equations. a. b. Write out the values of initial position, initial velocity, and acceleration. How many seconds will it take for the plane to reach takeoff speed? с. d. How far will the plane have to travel to get to takeoff speed? will the plane be able to get to take off before it gets to the end of the runway? е.

You are driving down a straight road at night in your McLaren MCL34 Formula 1 racecar at an entirely illegal speed of 98 m/s when Bambi and Thumper jump onto the road in front of you. Because you were texting while driving (also illegal), your reaction time is a rather slow; 1.3 seconds before your foot touches the brake. How far did you travel during this time? O a. 98 m O b. 127 m O c. 101 m O d. 134 m O e. 112 m Clear my choice

When Sam drove at 9.5 m/s on university blvd, she passed her friend, Jess who was riding a bike at 5.0m/s. As Sam was passing Jess, she started to slow down while Jess kept her constant speed. So Jess caught up to Sam after 3 seconds. a.) Determine the distance traveled by Jess when she caught up to Sam.

A safety measure when driving cars is to leave a separation of "3 s" with respect to the next car. This rule has made it possible to avoid many accidents. a. If a car travels at 60 km / h, what distance (in meters) will it travel in 3 seconds? Assuming there is an accident 20 m from where you are, what acceleration must you have to bring the car to a complete stop before reaching the accident?b. Repeat part a considering a speed of 90 km / hc. Repeat part a considering a speed of 120 km / hd. Repeat part a considering a speed of 150 km / h

An airplane decelerates at a uniform rate of 8.0 m/s2 (a = -8.0 m/s2), until it stops after traveling 483 m. Determine: a. how fast was the plane traveling before it began to decelerate? b. Express your answer in scientific notation and in at least 3 significant figures.

Ilya and Anya each can run at a speed of 8.00 mphmph and walk at a speed of 3.10 mphmph . They set off together on a route of length 5.00 milesmiles . Anya walks half of the distance and runs the other half, while Ilya walks half of the time and runs the other half.   A.) How long does it take Anya to cover the distance of 5.00 milesmiles ? Express your answer numerically, in minutes.   B.) Find Anya's average speed. Express Anya's average speed save,Anyasave,Anya numerically, in miles per hour.   C.) How long does it take Ilya to cover the distance? Express the time tIlyatIlya taken by Ilya numerically, in minutes.   D.) Now find Ilya's average speed. Express Ilya's average speed save,Ilyasave,Ilya numerically, in miles per hour.
