At t=0, a ball is thrown with an initial velocity of magnitude 15ms-1 at 75° to the horizontal (upwards). a) Calculate the magnitudes of the vertical and horizontal components of its initial velocity. b) Calculate the magnitude of the vertical component of velocity of the ball at t=0.5s. c) Calculate the magnitude of the vertical component of velocity of the ball at t=2.0s.

Step 1
Calculating, we get \(v_{0x} = 15 \, \text{m/s} \times \cos(75^\circ) = 3.9 \, \text{m/s}\). Show more…

A ball is thrown with an initial velocity of 20.0 m/s in a direction that makes a 65.0° angle with the horizontal (Assume it was thrown from ground level). a) What is the maximum height of the ball relative to the ground? b) What distance away from its initial location does the ball strike the ground? c) What is the ball's velocity as a magnitude and direction at t = 1.75 s?

It was observed that a tennis ball when served horizontally 7.5 ft above the ground strikes the smooth ground at $B 20 \mathrm{ft}$ away. Determine the initial velocity $v_{A}$ of the ball and the velocity $v_{B}(\text { and } \theta)$ of the ball just after it strikes the court at $B$. Take $e=0.7$.
Shot into the Air A ball is shot from the ground into the air. At a height of $9.1 \mathrm{~m}$. Its velocity is observed to be $\vec{v}=(7.6 \mathrm{~m} / \mathrm{s}) \hat{\mathrm{i}}+$ $(6.1 \mathrm{~m} / \mathrm{s}) \hat{\mathrm{j}}$ (i horizontal, $\hat{\mathrm{j}}$ upward). (a) To what maximum height does the ball rise? (b) What total horizontal distance does the ball travel? What are (c) the magnitude and (d) the direction of the ball's velocity just before it hits the ground?
