Question

the position of an object moving along x-axis is given by x is equal to a + b ka whole square where a is equal to 8.5 m b is equal to 2.5 M per second square and T is measured in seconds what is the velocity at t is equal to zero II and t is equal to 22 second? What is the average velocity between t is equal to 2 S and T is equal to 4 yes please please please tell me how to find the instantaneous velocity in this question only this question is for more and more clocks 100 points and whoever will give correct and quick answer will be worked as BRAINLIEST

Answer 1

Hy sis, here's ur ans...
X = a + bt^2
v = 2bt

Velocity at t = 0 is 0
Velocity at t = 2s is = 2*2.5*2 = 10 m/s

At t = 2s
x = 8.5 + 2.5*2^2
x = 18.5m

At t = 4s
x = 8.5 + 2.5*4^2
x = 48.5m

Average velocity = (48.5 - 18.5) / 2 = 18m/s
