Which of the following equation represents the motion of a body moving with constant finite acceleration ? In these equation, y denotes the displacement in time t and p.q and r the arbitary constants ?

Options

A. y=(p + qt)(r + pt)
B. y= p + tqr
C. y= (p + t)(q + t)(r +1)
D. y= (p +qt)r

Answer

A, B, C

Explanation

`y=x^(2), y_(x=1/2)=1/4, (dy)/(dt)=2x(dx)/(dt)=2x v_(x)`
`v_(y)=2xx1/2xx4(at x=1/2, v_(x)=4)`
`v_(y)=4m//s, vec(v)_(x=1/2)=4hat(i)+4hat(j), |vec(v)|=4sqrt(2)`
Slope of line `4x-4y-1=0` is `tan 45^(@)=1` and also the slope of velocity is 1.
