PROJECTILE

A stone is projected upward at 30° to the horizontal from a point 175 meter, above the ground with initial velocity of 20 m/s.

Given:

v¡ = 20 m/s
θ = 30°
g = 9.8 m/s²

A. The range of the projectile

$R = \displaystyle \frac{v_{i}\:^{2} \sin2 \theta}{g}$

$R = \displaystyle \frac{(20 \: m/s)^{2} \sin 60^{\circ}}{9.8 m/s^{2}}$

$R = \displaystyle \tt 35.35 \: m$

Answer: $\large \sf \bold{ \blue{35.35 \: m}}$

B. The time of flight

$t = \displaystyle\frac{2v_{i} \sin \theta}{g}$

$t = \displaystyle\frac{2(20 \: m/s) \sin 30^{\circ}}{9.8 m/s^{2}}$

$t = \displaystyle \tt 2.04 \: s$

Answer: $\large \sf \bold{ \blue{2.04 \: s}}$
