The easiest way is to solve for the initial vertical velocity using trigonometry, and then use the appropriate kinematics equation to determine the time. To solve this question, we need to find the time that it takes the ball to reach this height. The trajectory of a projectile launched from ground is given by the equation y = -0. Any projectile has a vertical velocity of zero at the peak of its flight. For now, theres a lot of different variations of problems and project on motion, and it might seem that theres different ways to solve them. You absolutely will need to know how to solve problems. This is a super important topic in physics. 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? Hey, guys, for the next couple videos, were really talking about projectile motion. The Physics Classroom, The Laboratory, Projectile Problem-Solving Students use an online application to master three types of horizontally-launched projectile 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. An interactive html 5 applet may be used to better understand the projectile equations. Solution: This is a projectile motion problem, a type of motion in which, without air resis- tance, we have ax 0 and ay g. ![]() ![]() These problems may be better understood when Projectile problems are presented along with detailed solutions.
