7. How many seconds would it take a car travelling at
100.0 km/h to travel a distance of 16 m?

Respuesta :

Answer: 0.58 s

Explanation: Solution attached:

Convert first 100.0 km/h to m/s

100.0 km/h x ( 1000 m / 1 km ) x ( 1h / 3600s ) + 27.8 m/s

Use v= d / t and derive too find t:

t = d / v

 = 16 m / 27.8 m/s

 = 0.58 s

cancel out meters and the remaining unit is in seconds.

Answer: Time, t = 0.57 seconds

Explanation:

Speed of the car, v = 100 km/h = 27.77 m/s

Distance covered by the car, d = 16 m
