Answer to Question #176843 in Mechanics | Relativity for Catherine Chileshe

Question

A projectile is fired at an angle of 60 degrees with initial velocity of 100m/s find, time of asent

Answer 1

In component form, initial velocity $u_o=100sin60^0$

time of ascent $=\frac{2u_{o}}{g}=\frac{2\times 100sin60^{0}}{9.8}= 17.67s$
