Projectile Motion: Practice Problems with Solutions Physexams.com 1. A missile is shot horizontally from the top of a 500m cliff with an initial speed of 300m/s (a) Find the time it takes for the missile to hit the ground. (b) What is the range of the missile? (c) Calculate the velocity of the missile just before it hits the ground.
A projectile is fired with a velocity of 20ms-1 at an angle of 25° above the horizontal. Any air resistance can be ignored. a) Calculate or find: i) The initial vertical component of the projectiles velocity. ii) The initial horizontal component of the projectiles velocity. b) The maximum height reached by the projectile at point X.
Step 1: Determine how long the object was in the air. Use the equation d = 1⁄2 at2 and solve for time. Rearrange the equation into. 1. = 2. 2 = 2. = 2. Our shortcut equation for finding the time an object hits the ground from a height of “d”. top of a 122.5 m cliff. How far from the base of the cliff will the object strike the ground?
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. a) Find the initial velocity and the angle at which the projectile is launched.

PROJECTILE QUESTIONS (a) What is a projectile? (b) What is special about its motion? (c) A projectile is fired horizontally at 100m/s. (i) How long will it take it to travel a horizontal distance of 50m? (ii) What will be its vertical velocity when it hits the ground? (iii) What will be its average vertical speed?
A projectile is launched with an initial velocity of 1.5 km s–1 at an angle θ. The target is located at a distance of 3000 m and on the same level. The projectile strikes the target after 4.0 s. a Determine the horizontal velocity of the projectile. b Calculate the value of θ.
