Question

ifx=5t² and y =2t+2,then find the relation between x and y.​

Answer 1

Answer:

x=5t  

2

+18t

(1)v=  

dt

dx

​

=10t+18

​

 

att=2s,v=10×2+18=38m/s

(2)Average,velocity=  

time

displacement

​

 

att=2,x=5(2)  

2

+18×2=56m

t=3,x=5(3)  

2

+18×3=99m

Averagevelocity=  

3−2

99−56

​

=43 m/s
