Shows `(x,t),(y,t)` diagram of a particle moving in 2 dimensions If the particle has a mass of `500g` find the force (direction and magnitude) acting on the particle . |
Answer» As `(x,t)` diagram of particle is a st line , motion along X-axis is unifrom From ` x = ut, u = (x)/(t) = (2)/(2) = 1m//s` Force along X-axis is zero The `(y,t)` diagram is a parabola. If a is unifrom acceleration along Y-axis then from ` y = (1)/(2)at^(2)` `4 = (1)/(2) a x 2^(2), a = 2 m//s^(2) ` As `F = ma :. F = (500)/(1000) xx 2 = 1 N` along Y-axis . |
