Answer 1

Answer:

what is this ?

plz type and tell your questions

Answer 2

Answer:

Velocity of bus V  

b

​

=0 , Velocity of cyclist V  

c

​

=20m/s,  

Acceleration of bus a  

b

​

=2m/s  

2

 Acceleration of cyclist a  

c

​

=0

Relative velocity V  

cb

​

=V  

c

​

−V  

b

​

=20m/s

Relative acceleration a  

cb

​

=a  

c

​

−a  

b

​

=−2m/s  

2

 

Relative separation =96m

Using s=ut+

​

2t

   ⇒t

−20t+96=0

Solving the equation , we get t=8s and t=12s

Hence, after 8s, cyclist will overtake the bus.
