Question

A race car travels with a constant tangential speed of 82.6 m/s around a circular track of radius 667 m. Find the magnitude of the total acceleration.

Answer 1

Answer:

TOTAL ACCELERATION =10.229m/s²

Step-by-step explanation:

total acceleration = $\sqrt{centripetal accleration^{2} +tagential acceleration^{2} }$

since tangential speed is constant , tangential acceleration =0

Thus total acceleration = centripetal acceleration.

centripetal acceleration = v²/r

v=82.6m/s  , r= 667m

centripetal acceleration = 82.6²/667

centripetal acceleration = 10.229m/s²

TOTAL ACCELERATION =10.229m/s²
