Question

8. The position of an object moving on a
straight line is defined by the relation ya
{ x = t3 - 2t² - 4t Determine
a) the average velocity during the interval of 1 sec
to 4 second.
b) the velocity at t= 1sec and t =4 sec
c) the average acceleration during the interval of 1 sec
d) the acceleration at t= 4 second
e) the distance travelled in 4 second​

Answer 1

Answer:

The position of an object moving on a straight line is defined by the relation

, where x is expressed in meter and t in second. Determine <br> (a) the average velocity during the interval of 1 second to 4 second. <br> (b) the velocity at t = 1 s and t = 4 s, <br> (c) the average acceleration during the interval of 1 second to 4 second. <br> (d) the acceleration at t = 4 s and
