A projectile is launched into space at an angle of `60^(@)` with an initial speed of `200ms^(-1)`. Calculate
range of the projectile `(g=9.8ms^(-2))`.

Text Solution

Verified by Experts

Range of projectile,
`r=(V_0^2sin2theta)/g` i.e `R=(200xx200xxsin2(60)^(@))/(9.8)," " sin120^(@)=1/2`
`=(40000xx0.5)/(9.8)=2040.8m`
R=2.041 km
