9. The position of an object moving along x-axis is given by x = a + b where a = 8,5 m and b = 2.5 m s? and is measured in seconds. Its velocity at 1=2 s and the average velocity between 1-2 s and 4 sis (a) 2 ms ,5 ms (b) 5 ms, 10 ms! (c) 10 ms!, 15 ms! (d) 10 ms, 20 m

The position of an object moving along x-axis is given by x = a+ bt^2 , where a = 10m, b = 3 ms^-2 , and 't' is measured in second. What is the average velocity between t = 2s and t = 4s?

The position of an object moving along x-axis is given by x=a +bt^(2) , where a=8.5 m and b=2.5 ms^(-2) and (t) is measured in seconds. What is the velocity at t=1= 0 s and t=2.0 s? What is the average velocity between t=2.0s and t=4.0 s ? a) 5 m/s b) 10 m/s c) 15 m/s d) 20 m/s

The position of an object moving along x-axis is given by x =a+bt^(2) where a =8.5 m, b=2.5 ms^(-2) and t is measured in seconds.Then which of the following is true ?

The position of an object moving along x-axis is given by x =a + bt ^(2) where a 8.5 m, b =2.5 ms ^(-2) and t is and t = 2.0 s. What is the average velocity between t = 2.0 s and t = 4.0s ?

The position of an object moving along x axis is given by x =a+ bt^2 here a= 8.5 m, b = 2.5 ms^(-2) and t is time in second. Calculate the velocity at t = 0 and t = 2 s and also calculate average velocity between t = 2 s and t = 4 s.
