Starting from origin at t=0, with initial velocity 5 hat(j) m//s, a particle moves in the x-y plane with a constant acceleration of (10 hat(i) - 5hat(j))m//s^(2). Find the coordinates of the particle at the moment its y-coordinate is maximum. |

Answer» (5m, 5m) `y_(y) = u_(y) + a_(y) t rArr 0= 5- 5t rArr t= 1` `x= u_(x) t + (1)/(2) a_(x) t^(2) = 0 + (1)/(2) (10) (1)= 5` `y= u_(y) t + (1)/(2) a_(y) t^(2) = 5(1) + (1)/(2) (-5) (1) = 2.5` |
