Acceleration, speeds up A car is stopped at a red light. When the light turns green, the car speeds up to 80 m/s in 5 s. What is the acceleration of the car?
Acceleration, speeds up What is the acceleration of a train that travels from 100m/s to 120m/s in 10s?
Acceleration, speeds up A boat accelerates at a rate of 6.0 m/s 2 down the river. How much time will it take the boat to speed up to 70 m/s?
Acceleration, Slows down Carlos throws a boomerang into the air with an initial velocity of 5 m/s. The boomerang takes 5 s to reach a velocity of 3 m/s. What is the boomerang’s acceleration?
Acceleration, gravity A gorilla falls out of the tree with an acceleration of 25 m/s 2. If she hits the ground in 5 s, what is the poor gorilla’s change in velocity?
Acceleration, gravity An apple falls from a tree and reaches the ground in 4seconds with a velocity of 40m/s. What is the acceleration?
Velocity and Acceleration If or v = at v = gtg = -10m/s^2
Position equation A race car accelerates uniformly from 18.5 m/s to 46.1 m/s in 2.47 seconds. Determine the acceleration of the car and the distance traveled. Problem 4: 6/Sample-Problems-and-Solutions
Gravity Distance = (1/2)(acceleration)(time) 2 d = (1/2)at 2
Position equation A feather is dropped on the moon from a height of 1.40 meters. The acceleration of gravity on the moon is 1.67 m/s^2. Determine the time for the feather to fall to the surface of the moon. Problem 5: Problems-and-Solutionshttp:// Problems-and-Solutions
