The formula for average velocity
What is avg. velocity = displacement/time
The velocity of a car increases from 4.0 m/s at 1.0 s to 12.0 m/s at 4.5 s. What is the car’s average acceleration between 1 and 4.5 s?
What is 2.3 m/s2
Ignore air resistance. If a ball is thrown straight up and falls straight back down, what is the velocity of the ball at the peak of its path (its highest point)? What is its acceleration?
What is 0 m/s and 9.8 m/s2 (downward)
A hiker travels 3 miles to the East, then 2 miles to the West, then 5 miles to the East, then 4 miles to the West. What is the distance traveled? What is the displacement of the hiker?
distance = 14 miles
displacement = 2 miles East
What is the formula for calculating displacement given constant acceleration
What is d = vi*t + 1/2*a*(t)2
