A ball is thrown upward in the air and falls back down to the ground. State what happens to the velocity at the highest point.
What is the velocity is zero?
100
A ball is released from rest from an elevated position and free-falls towards the ground. If it strikes the ground after 5.4 seconds, then what was the height from which the ball was released?
What is
Deltay = V_i*t - 1/2*g*t
100
Determine the acceleration from t = 2-4 s.
What is -1 m/s/s?
100
A ball is thrown upward with a speed of 20 m/s. How long will it take to reach the highest point?
What is 2.04 s?
200
A ball is thrown upward in the air and falls back down to the ground. State what happens to the velocity when the ball rises upward.
What is the velocity decreases?
200
A car traveling with an initial velocity of 6 m/s accelerates for 5 seconds and travels a distance of 65 m. What is the car’s final velocity?
What is
Deltax = 1/2 (V_i + V_f)*t
200
Determine the acceleration from t = 4-6 s.
What is 0 m/s/s?
200
A ball is dropped from rest 10 m above the ground. How fast will the ball be going just before it hits the ground? *INCLUDE DIRECTION
What is 14 m/s downward?
300
A ball is thrown upward in the air and falls back down to the ground. State what happens to the velocity when the ball falls back to the ground.
What is the velocity increases?
300
A ball is thrown upward with a speed of 20 m/s. How long will it take to reach the highest point?
What is
V_f = V_i - g*t
300
A car traveling with an initial velocity of 6 m/s accelerates for 5 seconds and travels a distance of 65 m. What is the car’s final velocity?
What is 20 m/s away from the origin?
300
Explain what happens to the impulse and kinetic energy as a ball thrown in the air travels upward in the air.
What is the impulse will decrease due to a loss in momentum and the kinetic energy will decrease because the ball slows down on the up?
400
A ball is thrown upward in the air and falls back down to the ground. State the direction of velocity and acceleration when the ball is on the rise upward.
What is the acceleration is downward and the velocity is upward?
400
A car traveling with an initial velocity of 6 m/s, accelerates at 2 m/s/s, for 6 seconds. How far did the car travel?
What is
Deltax = V_i*t + 1/2 *a*t^2
400
An object is moving to the right with a decreasing velocity. State the direction of acceleration.
What is the direction of acceleration is left (negative)?
400
A bowling ball and a baseball are dropped from the same cliff (50 m). Ignoring air resistance, state which object will hit the ground first.
What is neither, they will hit the ground at the same time.
500
A ball is thrown downward off of a cliff. State the direction of the velocity after the ball is thrown and draw a v vs t graph.
What is the velocity is negative?
500
A ball is dropped from rest 10 m above the ground. How fast will the ball be going just before it hits the ground?
What is
V_f ^2 = V_i ^2- 2*g*Deltay
500
A car traveling with an initial velocity of 6 m/s, accelerates at 2 m/s/s, for 6 seconds. How far did the car travel?
What is 72 m away from the origin?
500
A ball is released from rest from an elevated position and free-falls towards the ground. Assuming negligible air resistance, what is the ball's speed after 2.5 seconds? *INCLUDE DIRECTION
What is 24.5 m/s downward?
