Question

the position time graph of an object in uniform motion is given below calculate the velocity with which the object is moving and ( hint : calculate the slope of the given x-t graph )​

Answer 1

Answer:

as the slope is a straight line that means velocity is constant throughout!!

now slope of displacement- time graph gives velocity

slope = velocity = ∆x/∆t

$velocity = slope = (x2 - x1) \div (t2 - t1)$

v = (20-80) ÷ (4-0)

v = -60 ÷ 4

v = -15 m/s

or v= 15 m/s is negative direction
