Answer:
Energia cinetica=187.5 [J]
Explanation:
La energia cinetica se define por medio de la siguiente ecuacion:
Debemos convertir las unidades de kilómetros por hora a metros por segundo
Reemplazamos en la ecuacion de energia cinetica.
Explanation:
Given that,
Initial speed of the car, u = 88 km/h = 24.44 m/s
Reaction time, t = 2 s
Distance covered during this time,
(a) Acceleration,
We need to find the stopping distance, v = 0. It can be calculated using the third equation of motion as :
s = 74.66 meters
s = 74.66 + 48.88 = 123.54 meters
(b) Acceleration,
s = 37.33 meters
s = 37.33 + 48.88 = 86.21 meters
Hence, this is the required solution.
