Question

A car is traveling at a constant

speed of 12 m/s. When the driver
accelerates, the car reaches a speed
of 26 m/s in 6 s. What is the average
acceleration of the car?
OB.2.3 m/s/s
A. 2 m/s/s
C.4.3 m/s/s
D. 84 m/s/s

Answer 1

Step-by-step explanation:

initial velocity u = 12m/s

final velocity v = 26m/s

time t = 6s

v = u + at

26 = 12 + 6a

26 - 12 = 6a

14/6 = 6a/6

a= 14/6

a = 2.33m/s^2
