Question 1 of 19
1. Question
The position of a particle as it moves along the x axis is given for t > 0 by x = (t 3 – 3t 2 + 6t) m, where t is in s. Where is the particle when it achieves its minimum speed (after t = 0)?
CorrectIncorrect

Question 4 of 19
4. Question
A rock is thrown from the edge of the top of a 100ft tall building at some unknown angle above the horizontal. The rock strikes the ground a horizontal distance of 160 ft from the base of the building 5.0 s after being thrown. Assume that the ground is level and that the side of the building is vertical. Determine the speed with which the rock was thrown.

6. Question
An object is thrown downward with an initial (t = 0) speed of 10 m/s from a height of 60 m above the ground. At the same instant (t = 0), a second object is propelled vertically upward from ground level with a speed of 40 m/s. At what height above the ground will the two objects pass each other?
CorrectIncorrect
