Question

The change in velocity of motor bike is 54 km/h in one minute. then acceleration is
​

Answer 1

Answer:

Step-by-step explanation:

u=0m/s

v=54m/s

t=60s

a=v-u/t

54-0/60

54/60=0.9m/s

Answer 2

Answer:

Hey...!!!

Here is ur answer...!!!

We know....

v = u - at

So here

u = 0

v = 54 km/hr

t = 1 min = 60 s

a = ?

First we need to convert v into its SI units i.e. m/s

We can do this by multiplying v by 5/18...

So Let's do that ....

v = 54 km / hr

v = 54×5/18

v = 5×3

v = 15 m/s...

According to formula....

15 = 0 - a(60)

a = 15/60

a = 1/4

a = 0.25 m/s^2

Hence Acc. = 0.25 m/s^2....
