A person swims to the other end of a 20 m long pool and back. What is their displacement?

• 0 m (since displacement is the change in position and they return to the starting point)

• 20 m (the length of the pool)

• 40 m (the total distance swum)

• 10 m (half the length of the pool)

A rock falls 15 m. Is this vertical or horizontal motion? What is the displacement of the rock?

• Vertical motion; Displacement = 15 m downward

• Horizontal motion; Displacement = 15 m to the right

• Vertical motion; Displacement = 15 m upward

• Horizontal motion; Displacement = 15 m to the left

A car moving 12 m/s stops in 3 seconds. Vf =

• 0 m/s (since the car stops)

• 3 m/s

• 6 m/s

• 12 m/s

You throw a rock into the air and catch it as it returns. What is the displacement of the rock?

• 0 m (returns to starting point)

• 5 m (height reached)

• 10 m (total distance traveled)

• -5 m (negative height)

• t, Δx = (Vf + Vi)/2 * t

• a, Δx = Vi * t + 0.5 * a * t²

• t, Δx = Vf * t - 0.5 * a * t²

• t, vf2​=vi2​+2aΔx

• Vi, Δx = Vi * t + 0.5 * a * t²

• t, Δx = Vf * t + 0.5 * a * t²

• vi, Δx = Vf * t - 0.5 * a * t²

• Δx, Δx = Vi * t + a * t

• Δy, Vf = Vi + a * t

• Δx, Vf = Vi + a * t

• t, Vf = Vi * a * t

• d, Vf = Vi / a * t

In 10 seconds a car accelerates 4 m/s² to 60 m/s. How fast was the car going before it accelerated?

• Vi = 50 m/s

• Vi = 10 m/s

• Vi = 40 m/s

• Vi = 20 m/s
