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.
PROJECTILE MOTION WORKSHEET. 1. A stone is thrown horizontally at 8.0 m/s from a cliff 80m high. How far from the base of the cliff will the stone strike the ground? 2. A toy car moves off the edge of a table that is 1.25m high.
Randomized practice problems for calculating the range of a projectiles fired at an angle.
Find out how including air resistance affects the maximum range, and the best angle to shoot at for maximum range. Do you think it's greater than or less than 45 degrees? Find out.
Some key terms to know, and how to calculate them, are: Time of flight: how long the projectile is in the air. Maximum height attained: the height at which the projectile is momentarily at rest. Range: the horizontal distance travelled by the projectile. How to find the time of flight, maximum height and range.
