A car starts from stop and travels 449 meters in 35 seconds.  What is the average acceleration of the car? The average acceleration is:     What is the final velocity of the car? The final velocity is:

A speeder traveling at 40 m/sec along a straight road sees a police car in the distance.  He applies the brakes and the car stops in 160m. a) How long does it take for the car to stop? b) What was the car’s acceleration?

A rock is dropped from a bridge to the water below. It takes 5.25 deconds for the rock to hit the water. What is the velocity of the rock as it hits the water in metres per second? How far from the water is the bridge (in units of metres to 3 decimal places)? State at the start of the problem which direction is positive (using the up arrow or down arrow) Make a list of all given values, units, and variables they represent. Write the general form of the equation you are going to use. Insert the known variables and solve.

A vehicle accelerates down an on ramp and eventually reaches highway speed. The position of the vehicle is described by the following equation:x(t) = At2/(t+B) a)Write an expression for the vehicle’s instantaneous velocity as a function of time.  b)What is the vehicle’s velocity after accelerating for 7 seconds? The equation’s parameters are as follows. A = 35 m/s B = 23 s  c)After accelerating, the velocity of the vehicle will begin to level off at highway speed. Write an expression for the vehicle’s velocity after it has been accelerating for a long time.  d) Determine the value of the vehicle’s velocity after it has been accelerating for a long time. The equation’s parameters are as follows. A = 35 m/s B = 23 s

A new prototype car is first test driven at 75 m/s for 9 seconds and then it is immediately slowed down to 25 m/s and drive at this speed for 45 seconds. What is the average velocity of prototype car during the entire test drive in m/s?

Basam is standing on the edge of a cliff and tosses her physics book upward with a speed of 22.0 m/s. It hits the ground at the base of the cliff 6.0 s later. Create a VELOCITY-TIME graph that represents this scenario. You may assume that the acceleration of the textbook is -9.81 m/s². Use the graph to determine a) the height of the cliff. b) the speed of the book when it impacts the ground. DO NOT use kinematics formulas to solve this problem. This task is assessing your understanding of GRAPHING to represent accelerate motion.

The distance from poplar bluff to Columbia is approximately 250 miles. If you take 4 hours to drive from poplar bluff to Columbia what is your average speed? If you take 6 hours to return from Columbia to poplar bluff what is your average speed? What is the average speed of the whole trip?

A car is driven 12.0km North and then 4.00km East. a)  What is the car’s displacement ?  b) If the entire trip took 30 mintues, what was the average speed of the car ?   c)  What was the average velocity of the car ?

A motorist starts from rest and traveled as seen in the speed-time graph. The total distance traveled and the average velocity in m/s for the distance traveled is 1.5 3.0 4.5 6.0 7.5 Time in minutes Select one: O a. 7.5 km, 4.5 m/s b. 10 km, 1.5 m/s c. 4.5 km, 10 m/s Reply... Speed in km/h :
