An object moves along the x–axis. Its x coordinate is given as a function of time as
x = 7 t – 3t2
where x is in metre and t is in second. Its average speed over the interval t = 0 to t = 4 s is
x = 7 t – 3t2
where x is in metre and t is in second. Its average speed over the interval t = 0 to t = 4 s is
- 5 m/s
- – 5 m/s
- \(-\frac{169}{24} m / s\)
- \(\frac{169}{24} m / s\)
Answer
(D) 169 24 m / s
