Problem :
What is the average velocity of the object on
[1, 4]
?
v _{avg} | = | = | |
= | 4 feet per second |
Problem :
What is the instantaneous velocity at
t = 1
and at
t = 4
?
Problem :
What is the total distance traveled on
[1, 4]
?
s() - s(1) = -3 - (- 6) = 3 feet .
The distance traveled on the second interval iss(4)-s() = 10-(-3) = 13 feet .
The total distance traveled is the sum of these two, which is 16 feet.Problem :
A ball is dropped vertically from a height of 100 meters. Assume that the acceleration
due to gravity has a magnitude of 10 m/s
^{2}
.
What is the velocity at
t = 2
?
Problem :
What is the position of the ball at
t = 2
?
