Choose Kinematic Equation

an object is traveling 3m/s and begins accelerating at a rate of 2m/s², what is the final velocity

• a=v/t

• v_f=v_i+at

• d=[(v_i+v_f)/2]t

• v_f²=v_i²+2ad

• d=v_i(t)+1/2a(t²)

Rocket-powered sleds are used to test the human response to acceleration. If a rocket-powered sled is accelerated to a speed of 444 m/s in 1.83 seconds, then what is the distance that the sled travels?

Choose the appropriate equation.

• d=1/2(v+v_o)t

• v²=v_o²+2ad

• d=v_ot+1/2at²

• v=v_o+at

An automobile with an initial speed of 4.30 m/s accelerates uniformly at the rate of 3.0 m/s².  Find the final speed after 5.0 s.

• v_f = v₀ + at

A car is traveling to the right with a speed of 29​​m/s when the rider slams on the accelerator to pass another car. The car passes in 110 m with constant acceleration and reaches a speed of 34m/s. We want to find the acceleration of the car as it sped up. What equation should you choose?

• vf=vi+at

• x=vit+1/2at²

• vf²=vi²+2aX

• x=((vf+vi)/2)t

A car traveling initially at +7.0 m/s accelerates uniformly at the rate of +0.80 m/s² for a distance of 245 m. What is its velocity at the end of the acceleration?

• v_f = v₀ + at

A car accelerates uniformly in a straight line from rest at the rate of 2.3 m/s². How long does it take the car to travel 55 m?

• v_f = v₀ + at

Turner’s treadmill runs with a velocity of -1.2 m/s and speeds up at regular intervals during a half-hour workout.  After 25 min (1500 s), the treadmill has a velocity of -6.5 m/s.  What is the average acceleration of the treadmill during this period?

• v_f = v₀ + at
