Practice Projectile Motion in Physics
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
Motion of an object thrown or launched, moving under gravity with an initial velocity.
A thrown ball follows a curved path—horizontal motion is steady, vertical is accelerated.
Example 1
mediumA ball is launched horizontally at 15 \text{ m/s} from a cliff 45 \text{ m} high. How far from the base of the cliff does it land? Use g = 10 \text{ m/s}^2.
Example 2
hardA projectile is launched at 40 \text{ m/s} at 30° above the horizontal. What is the maximum height and horizontal range? Use g = 10 \text{ m/s}^2.
Example 3
mediumA ball is kicked at 20 \text{ m/s} at 45°. What is the range? Use g = 10 \text{ m/s}^2.
Example 4
hardA ball is kicked horizontally off a 45 \text{ m} high cliff at 20 \text{ m/s}. Using g = 10 \text{ m/s}^2: (a) How long until it hits the ground? (b) How far from the base of the cliff does it land?
