Question

The motion of a particle restricted to move in a two dimensional plane is given by x = 2 cos pi t and y = 1 - 4 cos 2 pi t where x and y are in metres and t is in seconds. Show that the path of the particle is a part of parabola y = 5 - 2 x^(2). Find the velcoity and the acceleration of particle at t = 0 and t = 1.5 s.

Answer 1

Explanation:

hope it helps you...

.....

Answer 2

so ya what you have to do here is just take the x and just square get x2 and then put it in the show that equation hope it helps
