CW: Review for Solving Kinematics Problems

What is the first step in solving kinematics problems?

• Identify what information is known.

• Determine the unknown variable.

• Select the appropriate kinematic equation.

• Check if the answer makes logical sense.

• 0.51 m

• 1.28 m

• 2.55 m

• 5.0 m

A ball is tossed directly upward with an initial velocity of 5.0 m/s. What is the total time the ball spends in the air before returning to its initial release point? (Assume acceleration due to gravity is -9.8 m/s²).

• 0.51 s

• 1.02 s

• 2.04 s

• 5.0 s
