Question

Find the range of ball which, when projected with a velocity of 29.4 m s ^- 1 just passes over a pole 4.9 m high

plz friends give me answer plz​​

Answer 1

Answer:

first by using height and velocity calculate sin theta of projectile

h=u²sin²theta/2g

4.9=29.4²sin²theta/2×10

sin²theta=0.113

theta=20

now,

R=u²sin2theta/g

R=29.4²×sin40/10

R=55.55m
