What is 184 m?
A rock is dropped from the top of a cliff. It falls for 3.0 s before hitting the ground. This is the rock's final velocity just before it hits the ground.
What is -29.4 m/s?
Distance, speed, or time are examples of this type of quantity.
What is a scalar?
At what rate will a motorcycle increases its speed from 10 m/s to 34 m/s while traveling 176 m.
V0 =10 m/s
V = 34 m/s
Δx = 176 m
a = ?
A car is moving at 18 m/s and accelerates at 2.0 m/s² for 7.0 s. This is the equation used to determine the displacement of the car.
What is Δx=vot+1/2at2?
A runner increases her speed from 3.0 m/s to 9.0 m/s while covering a distance of 36 m. This is the runner's constant acceleration.
What is 1.0 m/s2?
A ball is thrown downward from a bridge with an initial velocity of -5.0 m/s. It continues accelerating due to gravity for 4.0 s. This is the ball's displacement during the 4.0 s interval.
What is -98.4 m?
Displacement, velocity, and acceleration are examples of this type of quantity.
What is a vector?
How long does it take a train accelerates from 8.0 m/s to 26.0 m/s at a constant rate of 1.5 m/s².
V0 = 8.0 m/s
V = 26 m/s
a = 1.5 m/s2
t = ?
A runner speeds up from 4.0 m/s to 10.0 m/s in 3.0 s. This is the equation used to find the runner's acceleration.
What is v=vo=at?
An airplane accelerates uniformly from rest and reaches a speed of 72 m/s after traveling 900 m down the runway. This is the airplane's acceleration and the time required to reach take off speed.
What is 2.88 m/s2 and 25.0 seconds?
A tennis ball is launched straight upward with an initial velocity of 24.0 m/s. This is the maximum height reached by the ball.
What is 29.4 m?
An object's directional speed before it accelerates positively or negatively.
What is initial velocity?
What height will an object reach if it's tossed vertically at 36 m/s.
V0 = 36 m/s
a = -9.81 m/s2
V = 0 m/s
Δx = ?
A soccer ball is kicked and speeds up from 4.0 m/s to 16.0 m/s while moving with constant acceleration for 2.0 s. This is the equation used to find the displacement of the ball.
What is Δx=1/2(vo+v)t?
A drag racer is traveling at 20 m/s when the driver begins accelerating uniformly. After 12 s, the racer has traveled 600 m. This is the racer's acceleration and the final velocity.
What is 5.0 m/s2 and 80 m/s?
A water balloon is launched straight upward from the top of a 20.0 m building with an initial velocity of 15.0 m/s. This is the maximum height of the balloon above the ground and the velocity of the balloon just before it hits the ground.
What is 31.5 m and -24.8 m/s?
