Physical Science Use the height formula in Example 10 to work the given problems. Note that an object that is dropped (rather than thrown downward) has velocity
Physical Science A ball is trown upward from ground level with an initial velocity of 100 feet per second. In how many seconds will the ball first reach the givne height?

- Time a Bullet Travels If the bullet in Problem 65 is traveling at 2,828 feet per second, how long does it take for the bullet to reach a height of 1,000 feet?arrow_forwardFaIIing-Body Problems Suppose an object ¡s dropped from a height h0 above the ground. Then its height after t second is given by h=16t2+ h0 , where h ¡s measured in feet. Use this information to solve the problem. A ball is dropped from the top of a building 96 ft tall. How long will it take to fall half the distance to ground level? How long will it take to fall to ground level?arrow_forwardThe Skydiver Again When a skydiver jumps from an airplane, her downward velocity, n feet per second, before she opens her parachute is given by = 176 1 0.834t, where t is the number of seconds that have elapsed since she jumped from the airplane. We found earlier that the terminal velocity for the skydiver is 176 feet per second. How long does it take for her to reach 90 of terminal velocity?arrow_forward
