3.calculate the linear velocity of the engine at 4mm from the maximum amplitude. determine the maximum linear velocity of the vibration. 1.Determine the angular velocity of the vibration spring. Ball has is pushed so that its initial velocity is 10 m/s and ball B is pushed so that its initial velocity is 15 m/s.Ī) Find the time it takes each ball to hit the ground. assume that the vibration can be moddeled by Simple harmonic motion. Two balls A and B of masses 100 grams and 300 grams respectively are pushed horizontally from a table of height 3 meters. How far from the cliff does the stone strike the ground A ball rolls off. Solution: The initial step in resolving any projectile motion. (b) the horizontal distance traveled by the ball. Find (a) the total time the ball is in the air. A skier leaves the horizontal end of a ramp with a velocity of 25.0 m/s E and lands 70.0 m from the base of the ramp. Upon reaching the edge of the table, it follows a parabolic path to the floor. The trajectory of a projectile launched from ground is given by the equation y = -0.025 x 2 + 0.5 x, where x and y are the coordinate of the projectile on a rectangular system of axes.Ī) Find the initial velocity and the angle at which the projectile is launched. A stone is thrown horizontally from a cliff 30m high with an initial speed of 20m/s. Problem (1): A person kicks a ball with an initial velocity of 15 m/s at an angle of 37° above the horizontal (neglecting the air resistance). A ball rolls with a speed of 2.0 m/s across a level table that is 1.0 m above the floor. The projectile hits the incline plane at point M.Ī) Find the time it takes for the projectile to hit the incline plane.Ī projectile is to be launched at an angle of 30° so that it falls beyond the pond of length 20 meters as shown in the figure.Ī) What is the range of values of the initial velocity so that the projectile falls between points M and N?Ī ball is kicked at an angle of 35° with the ground.Ī) What should be the initial velocity of the ball so that it hits a target that is 30 meters away at a height of 1.8 meters?ī) What is the time for the ball to reach the target?Ī ball kicked from ground level at an initial velocity of 60 m/s and an angle θ with ground reaches a horizontal distance of 200 meters.Ī ball of 600 grams is kicked at an angle of 35° with the ground with an initial velocity V 0.Ī) What is the initial velocity V 0 of the ball if its kinetic energy is 22 Joules when its height is maximum?ī) What is the maximum height reached by the ballĪ projectile starting from ground hits a target on the ground located at a distance of 1000 meters after 40 seconds.ī) At what initial velocity was the projectile launched? What Are the Arrow Flight Problems Problems with Detailed SolutionsĪn object is launched at a velocity of 20 m/s in a direction making an angle of 25° upward with the horizontal.Ī) What is the maximum height reached by the object?ī) What is the total flight time (between launch and touching the ground) of the object?Ĭ) What is the horizontal range (maximum x above ground) of the object?ĭ) What is the magnitude of the velocity of the object just before it hits the ground?Ī projectile is launched from point O at an angle of 22° with an initial velocity of 15 m/s up an incline plane that makes an angle of 10° with the horizontal.
