Straight Line Motion - Homework A particle is moving along a horizontal line with position function as given. Do an analysis of the particle's direction, acceleration, motion (speeding up or slowing down), and position. 1. s(t)=2+61-12 2. s(t)=13 -6t 2+91-4 3. s(t)=t 3 +9t2 -24t+1 4. 1+1 = 8321 2.6t2 feet 5. A 45-caliber bullet fired straight up from the surface of the moon would reach a height of s 2feet after t seconds. How after t seconds, On Earth, in the absence of air, its height would be s = 832t - 16t long would it take the bullet to hit the ground in either case?

A projectile is fired vertically upward (earth) from ground level with an initial velocity of 16 ft/sec. a. How long will it take for the projectile to hit b. How high will the projectile get? the ground? 8. A helicopter pilot drops a package when the helicopter is 200 ft. above the ground, rising at 20 ft/sec. a. How long will it take for the package to hit b. What is the speed of the package at impact? the ground? 9. A man drops a quarter from a bridge. How high is the bridge if the quarter hits the water 4 seconds later? 10. A projectile fired upward from ground level is to reach a maximum height of 1,600 feet. What is its initial velocity?
