A European sportscar dealer claims that his product will accelerate at a constant rate from rest to a speed of 100km/h in 6.00s. What distance will the sportscar travel during the 6.00-s acceleration period? (Hint: First convert speed to m/s.)
your professor purchased an electric sports car. according to him, his car accelerates at a constant rate from rest speed of 100 km/hr in 8.00 s. what distance will the sports car travel during 8 s acceleration period in units of m?
A Porsche sports car can accelerate at 9.3 m/s2. ONLY NEED HELP WITH C AND DON'T KNOW WHY IT'S INCORRECT (a) Is this acceleration greater than, less than, or equal to 9.3 km/s2? Less Than: Your answer is correct. (b) Determine the acceleration of a Porsche in ft/s2. 30.50 Correct: Your answer is correct. ft/s2 (c) Determine its acceleration in km/h2. 395280 Incorrect: Your answer is incorrect. km/h2 WHY IS THIS WRONG, AND WHAT IS THE CORRECT ANSWER?
So I know there is 4 different equationsfor kinematics. Can you pick the problems that use each one and write out how you do it? Especially 6 and 10 because those seem very hard. 1-D Kinematics Practice PHYS&114 Name: 1. A car starting from rest travels 231 m with a constant acceleration of 1.05 3. What is its 2.

1. Cheetahs can accelerate to a speed of 20.0 m/s in 2.50 s and can continue to accelerate to reach a top speed of 27.6 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 ?top in miles per hour (mi/h)(mi/h) . vtop = Starting from a crouched position, how much time ?accel does it take a cheetah...

Question 8 1 pts The driver of a car wishes to pass a truck that is traveling at a constant speed of 20.0 m/s. Initially, the car is traveling at a speed 25.0 m/s and its front bumper is a distance 24.0 m behind the truck's rear bumper. The car begins accelerating at a constant acceleration 0.6 m/s2, then pulls back into the truck's lane when the rear of the car is a distance 26.0 m ahead of the front...
