A car with initial velocity 7.2 m/s undergoes a constant acceleration. What is the acceleration (in m/s2 ) if the velocity of the car is 9.5 m/s 6 seconds later? Make sure to include a minus sign, if appropriate.

A jet fighter needs to be at the speed of 170mi/hr. What is the acceleration needed for the jet fighter to fly off the carrier in m/s²? A carrier runway is 300ft long. Assume that the aircraft experience uniform acceleration. How long will the jet fighter need to reach the needed speed in seconds

A particle moving along the x axis has acceleration in the x direction as function of the time given by a(t) = 6t²-t. For t=0 the initial velocity is 6.0 m/s. Determine the velocity when t = 1.0 s. Write here your answer. Include the units.

A VW Beetle goes from 0 to 54.0 mi/h with an acceleration of +2.35 m/s2. (a) How much time does it take for the Beetle to reach this speed? (b) A top-fuel dragster can go from 0 to 54.0 mi/h in 0.600 s. Find the acceleration (in m/s2) of the dragster.

A particle is moving in a straight line with its position given by x=(8.5m/s^2)t^2 + 6.0m. Calculate. a) The instantaneous velocity at t1=3.00s and t2=5.00s. b) It's average acceleration during the interval from t1=3.00s to t2=5.00s. c) Its instantaneous acceleration as a function of time.

I am also having trouble solving this problem since it includes the acceleration with its initial velocity without the final velocity. A car traveling with an initial velocity of 10 m/s accelerates at a constant rate of 2.2 m/s2 for 2 seconds.

I know I have to find the difference in their times to solve this practice problem.

A rocket-powered sled moves along a track, eventually reaching a top speed of 150 m/s to the west. It then begins to slow down, reaching a complete stop after slowing down for 4.21 s. What was the sled s average acceleration and velocity during the slowdown phase? 35.6 m/s^2 east, not enough information 0 m/s^2 0, 75 m/s west 35.6 m/s^2 west, not enough information

2.73. An automobile and a truck start from rest at the same instant, with the automobile initially at some distance behind the truck. The truck has a constant acceleration of 2.10 m/s², and the automobile an acceleration of 3.40 m/s². The automobile over- takes the truck after the truck has moved 40.0 m. (a) How much time does it take the automobile to overtake the truck? (b) How far was the automobile behind the truck initially? (c) What is the speed of each when they are abreast? (d) On a single graph, sketch the position of each vehicle as a function of time. Take x = 0 at the initial location of the truck.

A cart is given an initial velocity of 8.3 m/s and experiences a constant acceleration of 3.3 m/s?. What is the magnitude of the cart's displacement during the first 7 s of its motion?
