Atesla roadster car accelerates from rest at a rate of 7 m /s^2 for a time of 3.9 s calculate the distance it travels in time.

Accelerating from rest at the rate of 7 m/s^2 for 3.9 s ...

D= 1/2 a t^2

D= (3.5) (3.9)^2

D= 53.2 m

The car travels 53.2 meters in space, and 3.9 seconds in tme.

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.
