Find the volume of the solid obtained by rotating y = x² from x=0 to x=2 around the x-axis
Using the disk method, V = π∫(0 to 2) [f(x)]² dx = π∫(0 to 2) x⁴ dx. Evaluating: π[x⁵/5] from 0 to 2 = π(32/5 - 0) = 32π/5. The volume is 32π/5 ≈ 20.11 cubic units. The disk method works here because we're rotating around the x-axis and the function is non-negative on the interval.
A 2kg ball is thrown upward at 15 m/s. Ignoring air resistance, what is the maximum height and total time in the air?
At maximum height, velocity = 0. Using v² = v₀² - 2gh: 0 = 225 - 2(9.8)h, so h = 225/19.6 = 11.48 meters. For time to reach max height: v = v₀ - gt, so 0 = 15 - 9.8t, giving t = 1.53 seconds. Total flight time is double this (symmetry of projectile motion): 3.06 seconds. Note that mass doesn't affect the answer—the 2kg is irrelevant when air resistance is ignored, as all objects experience the same gravitational acceleration.
