Question

velocity of a bus is 50 kilometer per hour. what is the type of motion?​

Answer 1

Answer:

Given,

u=50km/h=

60×60

50×1000

=13.89m/s

v=0m/s

s=6m

From 2nd equation of motion,

2as=v

2

−u

2

a=

2s

v

2

−u

2

a=

2×6

0

2

−13.89×13.89

a=−16m/s

2

Now, u=100km/h=

60×60

100×1000

=27.78m/s

v=0m/s

From 2nd equation of motion,

2as=v

2

−u

2

s=

2a

v

2

−u

2

s=

−2×16

−27.78×27.78

s=24m
