2. A car accelerates along a straight road from rest to 90 km/h in 5.0s. What is the magnitude of average acceleration in meters per second squared. 3. If you are driving 110km/h along a straight road and look to the side for 2.0s, how far do you travel during this inattentive period? 4. At highway speeds, a particular car is capable of accelerating at about 1.8m/s?. At this rate, how long does it take to accelerate from 80km/h to...

1. The velocity of an object traveling along the x-axis changes from 20 m/s to 60 m/s in 10 seconds. What was the displacement that occurred during this time? 2. An object moving along the x-axis initially has a velocity of 60 m/s and is slowing rest? down at the rate of 4 m/s per second. How far (in meters) will it travel before coming to 3. An accelerating object travels 12 meters from rest in a certain time. How...
Please try to answer all questions and show work. Thank you. 1. A baseball player is warming up and tosses a ball straight up into the air. The ball travels up until it reaches some maximum height, and then falls back down to the player's hand. If we neglect air resistance, then the magnitude of the acceleration of the ball is? A. largest the moment after it leaves the players hand. B. smallgst the moment after it leaves the player's...

Part 2 (Choose 3 Nom TUTT I 1. A race car starts from rest and travels 400 meters in 5.2 seconds. When it crosses the finish line it has a final velocity of 140 m/s. a) What is the acceleration (a) of this car? b) How much time was spent traveling from 100 m/s to 140 m/s? c) If this car continued at this rate of acceleration, how long would it take for it to travel 800 meters? 2. A...
A car travelled for a total of 10 meters as he slows down uniformly from 60 mph to 20 mph. A) What is the magnitude of his deceleration in m/s?? B) Using the deceleration, initial speed, and final speed, calculate the amount of time it took him to decelerate from 60 to 20 mph.
