Question

figure shows a projectile trown with speed u=20 m/s at an angle 30 with horizontal from the top of a building 40m high. then the horizontal rqnge of projectile is?
Please tell with proper explanation

Answer 1

Yo Mate!!!!!

We Have Been Given All the Information That Needs For the Formula For Range!!!

u=20m/s

∅=30°

h=20m

Formula For Range

R=u²sin2∅

g

Let Us Assume g=10m/s²

Therefore

R=u²sin∅Cos∅

g

R=20²sin30°cos30°

g

R=400*(1/2)*(√3/2)

10

R=10√3 m

Hope this Is Correct and It Helpsᕙ[･۝･]ᕗ

Thank You
