If co-ordinates of a moving point at time t are given by x=a `(l+sint)` and `y=a(1-cost)`, then:A. the slope of accelration time graph is zeroB. the slope of velocity-time graph is constnatC. the direction of motion makes an angle t/2 with x-axisD. all of the above

Answer» Correct Answer - d
`(dx)/(dt)=a(1+cos t),(dy)/(dt)=sint`
`v=sqrt(((dx)/(dt))^(2)+((dy)/(dt))^(2))`
`a=sqrt(((d^(2)x)/(dt^(2)))^(2)+((d^(2)y)/(dt^(2)))^(2))`
