The position of an object moving along $x-$axis is given by $x=a+b{t}^2$, where $a=8.5\text{m}$ and $b=2.5{\text{ms}}^{–2}$ and $t$ is measured in seconds. What is average velocity between $t=2\text{s}$ and $t=4\text{s}$?

Q. The position of an object moving along x-axis is given by x = a + $b{t}^2$, where a = 8.5 m and b = 2.5 m $s^{-2}$ and t is measured in seconds. The average velocity of the object between t = 2 s and t = 4 s is

Q. The position of an object moving along $x-$axis is given by $x=a+b{t}^2$ where $a=8.5m$, $b=2.5m{s}^{-2}$ and $t$ is measured in seconds. What is its velocity at $t=0s$ and $t=2.0s$. What is the average velocity between $t=2.0s$ and $t=4.0s$.

Q. The position of an object moving along x-axis is given by x = $a+b{t}^2$ where a = 8.5 m, b = 2.5 $m{s}^{-2}$ and t is measured in seconds. What is its velocity at t = 0 s and t = 2.0 s.?

Q. The position of an object moving along x-axis is given by x = a + $b{t}^2$, where a = 8.5 m and b = 2.5 m $s^{-2}$ and t is measured in seconds. The instantaneous velocity of the object at t = 2 s is

Q. The position of a particle along along x-axis is given by $x=a+b{t}^2$, where a= 8.5 m, b = 2.5 m and $t$ is in seconds. What is its average velocity at t = 2.0 s? What will be its average velocity between $t=2s$ & $t=4s$?
