Question

At time t = 0 , a ball is thrown with initial speed v0 at an angle θ above the horizontal. Air resistance is negligible. Which of the following best represents the speed of the ball as a function of time t while the ball is in flight?

A \(v_0sinθ – gt\)

B \(v_0cosθ – gt\)

C \(\sqrt{v^2_0cos^2θ+(v_0sinθ−gt)^2}\)

D \(\sqrt{(v_0cosθ−gt)^2+v^2_0sin^2θ}\)

E \(\sqrt{(v_0cosθ−gt)^2+(v_0sinθ−gt)^2}\

Answer/Explanation

Ans:C
