If acceleration is constant and initial velocity of the body is 0, then choose the correct statement. Symbols have their usual meaning.

Options

A. `v prop sqrt(t)`
B. `v prop sqrt(x)`
C. `v prop t`
D. `v prop x^2`

Answer

B, C

Explanation

b,c. `u = 0, a= a_0`
`v_2 - 0_2 = 2a_0x`
`rArr v = sqrt(2a_0x) rArr v prop sqrt(x)`
`v = u + at rArr v prop t ` .
