A car moves in a straight line, at a time ( t_{1}=4 mathrm{~s} ) after the start of the movement, the car is at ( x_{1}=54 mathrm{~m} ), at ( mathrm{t}_{2}=8 mathrm{~s} ) after the start, it is at ( times_{2}=255 mathrm{~m} ) from the origin find the average velocity for the car

Question

Accepted Answer

Step:1 ：( bar{v} = frac{Delta x}{Delta t} )Step:2 ：( Delta x = x_{2} - x_{1} = 255 mathrm{~m} - 54 mathrm{~m} = 201 mathrm{~m} )Step:3 ：( Delta t = t_{2} - t_{1} = 8 mathrm{~s} - 4 mathrm{~s} = 4 mathrm{~s} )Step:4 ：( bar{v} = frac{201 mathrm{~m}}{4 mathrm{~s}} = 50.25 mathrm{frac{m}{s}} )
