Show that the pathprojectilemation is perabolic alsofind the expression for the time periodof projectile |
|
Answer» Answer: Let a body is projected with speed um/s inclined θ with horizontal line. Then, vertical COMPONENT of u, u y
=ucosθ Horizontal component of u
=usinθ acceleration on horizontal, ax=0 acceleration on vertical, ay=−g Now, USE formula X=u x
t X=ucosθ.t t=X/ucosθ--------------------------(1) Again, y=u y
t+1/2a y
t 2
y=usinθt−1/2gt 2
put equation (1) here, y=usinθ×x/ucosθ−1/2gt 2 ×x 2 /u 2 cos 2 θ =tanθx−1/2gx 2 /u 2 cos 2
y=tanθ.x−1/2gx 2 /u 2 cos 2 θ this equation is similar to standard equation of PARABOLA y=ax 2 +bx+c her, a,band c are constant So, A projectile motion is parabolic motion. solution |
