a car advertisement claims that a car can accelerate from rest to 70 km/hr in 7 seconds (hint convert to hours first) find the cars acceleration ​

Respuesta :

2.77 m/s^2

70 km/hr * 1 hr/60 sec * 1000 m/km = 19.44 m/s

accel. = (V(f) - V(i))/t

          = 19.44 / 7

accel. = 2.77 m/s^2

And by the way, this car sucks!!!!!!

Answer:

Explanation:

2.77 m/s^2

70 km/hr * 1 hr/60 sec * 1000 m/km = 19.44 m/s
