This problem is kinda big and just cant seem to start it off :/.
A new motion detector is used to graph the position of a sports car. If the themotion detector is not callibrated properly, it might give unrealistic graph data. The position of the car is described by the function S= 2t^3-21t^2 + 60, tE [0,6], where s is measured in meters and t in seconds. it is known the largest acceleration is 12 m/s ^2.
a) WHat is its initial velocity?
b)When is the car at rest?
c)When is the car at rest?
d)draw a diagram
e)Find the total distance traveled by the car in the first 6 seconds
f)Find the max acceleration of the car?
and i did a problem that i thought was to easy to be right just wondering if someone can second my answer, i doubt its right.
A stone is tossed down at 8 m/s from a edge of a cliff 63 m high how long will it take to hit the ground at the foot of the cliff?
3.8 seconds is what i got :/
Thanks for the help TJ
