1.	Time formula when two projectile are projected horizantally with different velocities
Answer» Explanation: Component of velocity ALONG the x-axis at any instant t. vx=ux + axt =u + 0 vx=u This means that the horizontal component of velocity does not change throughout the projectile motion. Component of velocity along the y-axis at any instant t. vy=uy + ayt =0 + gt vy=gt The displacement along x-axis at any instant t x=uxt + (1/2) axt2 x=uxt + 0 x=u t 4. The displacement along y-axis at any instant t y= uyt + (1/2) ayt2 y= 0 + (1/2) ayt2 y=1/2gt2 Equation of a trajectory(PATH of a projectile) We KNOW at any instant x = ut t=x/u Also, y= (1/2)gt2 Subsituting for t we get y= (1/2)g(x/u)2 y= (1/2)(g/u2)x2

Time formula when two projectile are projected horizantally with different velocities

Answer»

Explanation:

Component of velocity ALONG the x-axis at any instant t.

vx=ux + axt

=u + 0

vx=u

This means that the horizontal component of velocity does not change throughout the projectile motion.

Component of velocity along the y-axis at any instant t.

vy=uy + ayt

=0 + gt

vy=gt

The displacement along x-axis at any instant t

x=uxt + (1/2) axt2

x=uxt + 0

x=u t

4. The displacement along y-axis at any instant t

y= uyt + (1/2) ayt2

y= 0 + (1/2) ayt2

y=1/2gt2

Equation of a trajectory(PATH of a projectile)

We KNOW at any instant x = ut

t=x/u

Also, y= (1/2)gt2

Subsituting for t we get

y= (1/2)g(x/u)2

y= (1/2)(g/u2)x2
