1. A ball is dropped for the upper observation deck of a tower
450 meters above the ground. Its position above the ground at time
t seconds since it was dropped is given by the funtion
?(?) =−4.9?2 + 450.
A. What is the average velocity of the ball over the first three
seconds?
B. What is the velocity of the ball 5 seconds after it was
dropped?
c. How fast was the ball traveling when it hits the ground?...
A stone thrown downward with an initial velocity of 34.3 m/sec travel a distance of s meters, where:s(t)=4.9t + 34.3t and t is in seconds. If a stone is thrown downward at 34.3m/sec from a height of 294 m, how long will it take the stone to reach the ground?I am putting 294 in for t and trying to solve it that way. Is this correct? If not please let know where I am going wrong.
6. The tower of Pisa is 54.5 m tall. Assuming that Galileo dropped his object from rest from the top of the tower and that the effects of air resistance were negligible, how long would it take the object to fall, in seconds? What is the velocity of the object when it hits the ground? 7. A ball is thrown directly downward with an initial speed of 9.50 m/s from a height of 30.0 m. After what time interval does...
