Question

A body is projected with a velocity u m / s. Then find Range, height, time of flight for all cases.

Answer 1

For figure 1 :

Range of projectile $R=\frac{u^2\sin 2\theta }{g}$

Height $H=\frac{u^2{\sin }^2\theta }{2g}$

Time of flight $T=\frac{2u\sin \theta }{g}$

For figure 2 :

Time of flight $T=\sqrt{\frac{2h}{g}}$

Range of projectile $R=uT=u\sqrt{\frac{2h}{g}}$
