Question

Sam is riding his bike and spots a sinkhole. He slows his bike from 14.0 m/s to 2.0 m/s in 6.0 seconds. What is the bike's negative acceleration?
A
0.33 m/s2

B
2.0 m/s2

C
2.3 m/s2

D
12.0 m/s2

Answer 1

HEY MATE HERE IS YOUR ANSWER

OPTION ( C) 2.3 m/s2 ✔✔✔

Answer 2

Acceleration of the bike is, $a=-2\ m.s^2$

Explanation:

It is given that,

Initial speed of the bike, u = 14 m/s

Final speed of the bike, v = 2 m/s

Time, t = 6 s

We need to find the acceleration of the bike. We know that the rate of change of velocity of an object is equal to its acceleration. Its formula is given by :

$a=\dfrac{v-u}{t}$

$a=\dfrac{(2-14)\ m/s}{6\ s}$

$a=-2\ m/s^2$

Negative sign shows that the bike is decelerating or retardation. Hence, this is the required solution.
