- A child throws a ball from point A with an initial velocity v0 at an angle of 3° with the horizontal. Knowing that the ball hits a wall at point B , determine (a) the magnitude of the initial velocity, (b) the minimum radius of curvature of the trajectory.arrow_forwardBall A is thrown vertically upward from the top of a 30-m-high building with an initial velocity of 5 m/s. At the same instant, another ball B is thrown upward from the ground with an initial velocity of 20 m/s. Determine the height from the ground and the time at which they pass each other.arrow_forwardA group of students launches a model rocket in the vertical direction. Based on tracking data, they determine that the altitude of the rocket was 89.6 ft at the end of the powered portion of the flight and that the rocket landed 16 s later. Knowing that the descent parachute failed to deploy so that the rocket fell freely to the ground after reaching its maximum altitude and assuming that g = 32.2 ft/s2, determine (a) the speed v1 of the rocket at the end of powered flight, (b) the maximum altitude reached by the rocket.arrow_forward
- . In an elevator shaft, a ball is thrown vertically upward with an initial velocity of 18 m/s from a height of 12 m above ground. At the same instant, an open-platform elevator passes the 5-m level, moving upward with a constant velocity of 2 m/s. Determine (a) when and where the ball hits the elevator, (b) the relative velocity of the ball with respect to the elevator when the ball hits the elevator.arrow_forwardA model rocket is launched from point A with an initial velocity, V₀, of 85 m/s.

At the same instant, another ball is thrown upward with an initial velocity of 23 m/s. If the initial velocity of the first stone is 15 m/s, determine where and when the objects pass each other.arrow_forward
- A baseball pitching machine “throws” baseballs with a horizontal velocity v0. Knowing that height h varies between 788 mm and 1068 mm, determine (a) the range of values of v0, (b) the values of a corresponding to h= 788 mm and h= 1068 mm.arrow_forwardA boat is moving to the right with a constant deceleration of 0.3 m/s2 when a boy standing on the deck D throws a ball with an initial velocity relative to the deck which is vertical. The ball rises to a maximum height of 8 m above the release point and the boy must step forward a distance d to catch it at the same height as the release point. Determine (a) the distance d, (b) the relative velocity of the ball with respect to the deck when the ball is caught.arrow_forwardA golfer hits the ball with an initial velocity of 160 ft / s, at an angle of 25 ° to the horizontal. If the field of play descends at an average angle of 5 °, determine the distance d between the golfer and point B where the ball first touches the field.arrow_forward
