In the s-t equation `(s=10+20 t-5t^(2))` match the following columns.
`|{:(,"Column I",,"Column II"),((A),"Distancec travelled in 3s",(p),-20" units"),((B),"Displacement 1 s",(q),15" units"),((C ),"Initial acceleration",(r ),25" units"),((D),"Velocity at 4 s",(s),-10" units"):}|`

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
At `t = 3s, s=10+20(3)-5(3)^(2)=25` unit
`upsilon =(ds)/(dt)=20-10t`
At `t=4 s, upsilon = 20-10(4)=-20` unit
`a=(d upsilon)/(dt)=-10` units
