(a) Everywhere along the projectile’s path, (b) at the peak of its path, (c) nowhere along its path, or (d) not enough information is given.In a basketball game, a player attempts to apply what he learned in physics under projectile motion. He realizes that from his position, he needs to exert 25 m/s for the ball to hit the ring before the end of the last quarter of the game. At what angle must he position the ball, for him get 3 points for his team to win the match.Solve the problem. Unless stated otherwise, assume that the projectile flight is ideal, that the launch angle is measured from the horizontal, and that the projectile is launched from the origin over a horizontal surface A baseball is hit when it is 2.8 ft above the ground. It leaves the bat with an initial velocity of 149 ft/sec at a launch angle of 24°. At the instant the ball is hit, an instantaneous gust of wind blows against the ball, adding a component of -9.7i (ft/sec) to the ball's initial velocity. Find a vector equation for the path of the baseball.

- A baseball batter hits a long fly ball, giving it an initial velocity 45.0° above the horizontal. The ball rises to a maximum height of 14.8 m.An outfielder on the opposing team starts running at 7.60 m/s the instant the ball is hit. Calculate the farthest the fielder can be from where the ball will land so that it is possible for him to catch the ball, i.e. distance between fielder's original position and landing of the ball. Assume that the outfielder catches the ball at the same height at which it was hit, and that he begins running at the same time that it was hit.A projectile is launched with an initial speed of 30 m/s at an angle of 60° above the horizontal.What are the (a) magnitude and (b) angle of its velocity 2.0 s after launch, and (c) is the angle above or below the horizontal?
