- Your frined drops a tennis ball from her window (66.1 m above the ground). One second later you throw a rock(as a projectile) from the ground. The rock and the ball collide at x=32.6m, y=22 m measured from where the rock was thrown. a.) Determine how many second after the tennis ball is released the collision takes place. b.) Determine the velocity of the tennis ball at the time of the collision with the rock. c.) Determine the initial velocity of the rock in its component form.Solve the problem. PROVIDE THE GIVEN, REQUIRED, EQUATION, SOLUTION, AND FINAL ANSWER The charter day of Manila is usually celebrated with a fireworks display. In one of the displays, a shell was shot into the air with an initial speed of 87.0 m/s at an angle of 85.0º above the horizontal. The fuse was timed to ignite the shell just as it reaches its highest point above the ground. Solve for the following: a) height at which the shell explodes; b) time passed between the launch of the shell and the explosion c) horizontal displacement of the shell when it explodes.Problem 7: A1.85-kg falcon catches and holds onto a 0.67-kg dove from behind in midair.
- s on A runner is also on the track going in the same direction as the walker, running at an unknown constant speed.
