An automobile with an initial speed of 20 m/s accelerates at a rate of 5 m/s2. Use one of your kinematic equations and find how fast the car is moving after accelerating for 3 seconds.    a. 15 m/s.   b. 225.5 m/s.   c. 35 m/s.   d. 400 m/s.

What is the acceleration of a car that maintains a constant velocity of 100km/h for 10 seconds?   a. 10km/h.s   b. zero   c. 9.8 m/s^2   d. 10m/s^2

1. Rushin is waiting at a stoplight. When it finally turns green, Rushin accelerated from rest at a rate of a 2.00 m/s² for a time of 15 seconds. Determine the velocity of Rushin's car during this time period. -30 m/s? с. 7.5 m/s a. b. 30 m/s? d. 30 m/s 2. Ima is approaching a stoplight moving with a velocity of +30.0 m/s. The light turns yellow, and Ima applies the brakes and skids to a stop. If Ima has an acceleration rate of 8.00 m/s², determine the displacement of the car during the skidding process. 56.3 m cannot determine a. с. b. 240 m d. 4.3 m 3. A car slows down uniformly from a speed of 21.0 m/s to rest in 6.00 seconds. What was its average velocity? How far did it travel in that time? 10.5 m/s; 0.29 m 10.5 m/s; 63 m b. 21.0 m/s ;126 m a. с. d. cannot determine

5. An object is launched 15 m/s horizontally. A. Fill in the variables for the object. B. Solve for time in the y-direction. C. Since the x-direction is constant speed, solve for Ax.
