Practice Projectile Motion in Physics
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
Two-dimensional motion under gravity alone, where horizontal velocity is constant and vertical motion is uniformly accelerated — producing a parabolic path.
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?
