A car accelerates uniformly from a velocity of 20.0 km/h to 100.0 km/h in one minute. What is the average acceleration of the car in m/s2?

A pilot flies in a straight path for 1 h 30 min. She then makes a course correction, heading 10 degrees to the right of her original course, and flies 2 h in the new direction. If she maintains a constant speed of 640 mi/h, how far is she from her starting position?Your answer is______mi;

Alice is riding a bike at 12 mph, but decides to sprint.  She takes 0.7 s to accelerate to 19 mph.  At constant acceleration, calculate her acceleration, a/(ft/s2).  (Here are possibly convenient conversion aids: 60 mph = 1 mi/min = 88 ft/s.  This equation is exact.  You may wish to verify the equation.  One mile = 60*88 ft, and one hour = 60*60 s.)

The cheetah is considered the fastest running animal in the world. Cheetahs can accelerate to a speed of 21.8 m/s in 2.50 s and can continue to accelerate to reach a top speed of 28.8 m/s. Assume the acceleration is constant until the top speed is reached and is zero thereafter. 1) Express the cheetah's top speed in mi/h. (Express your answer to three significant figures.) answer: 64.2 2) Starting from a crouched position, how long does it take a cheetah to reach its top speed? (Express your answer to three significant figures.) answer: 3.31 3) How far does it travel in that time? (Express your answer to three significant figures.) answer: 47.5 4) If a cheetah sees a rabbit 120 m away, how long will it take to reach the rabbit, assuming the rabbit does not move? (Express your answer to three significant figures.)  answer: ?  tried 5.25 and 5.26  but does not work

A car has acceleration of 4 m/s2 and starts from 1.8 m/s. What is its speed after 7.4 seconds, in m/s? Represent your answer with 3 significant figures. (Your answer should NOT have any sign nor unit, the SI unit is already given in the problem statement.)

Cheetahs can accelerate to a speed of 20.2 m/s in 2.65 s and can continue to accelerate to reach a top speed of 29.0 m/s . Assume the acceleration is constant until the top speed is reached and is zero thereafter. Let the +? direction point in the direction the cheetah runs.Express the cheetah's top speed ?top in miles per hour (mi/h) .Starting from a crouched position, how much time ?accel does it take a cheetah to reach its top speed and what distance ? does it travel in that time?

a person walks for 1.00 hr at a speed of 2.00 mi/hr. he stops for 1.00 hr. he then starts walking again and covers 2.00 mi at a speed of 1 mi/hr. find the average speed of the trip answer with Correct number of significant digits

A person on a road trip drives a car at different constant speeds over several legs of the trip. She drives for 15.0 min at 50.0 km/h, 8.0 min at 80.0 km/h, and 30.0 min at 35.0 km/h and spends 25.0 min eating lunch and buying gas. (a) What is the total distance traveled over the entire trip (in km)? km (b) What is the average speed for the entire trip (in km/h)? km/h
