A body starts moving from origin at t = 0 with a velocity of 5 
in x-y plane under the action of force producing an acceleration of (3 
+ 2 
) m/s 2 , then y-co-ordinate in meters of body when x-co-ordinate is 84 m is.

Sol. x = u x t + 
a x t 2 ⇒ 84 = 5t + 
× 3t
2 ⇒ t = 6 sec
∴ y = u y t + 
a y t 2 Hence, y = 
× 2 × 36 = 36 m
