Question

a projectile is fired with 50m/s at an angle of 37⁰ find the time of ascent​

Answer 1

Answer:

time of ascent ta=3sec

Explanation:

we know that equation of motion

v=u+at

a=g=acceleration due to gravity=10m/S2

u=intial velocity=50m/s(given)

teta angle=37 degrees

final velocity must be zero because it will touches any object and becomes rest

so the vertical projectile will be sinteta
