A reflex action is an involuntary action which is a rapid and automatic response to stimuli. Walking is a voluntary action, which requires our thinking and is within our control.......
Explanation:
Angle of projection θ=30
0
initial velocity, μ=15 m/sec
a) Maximum height =
2g
μ
2
sin
θ
=
2×9.8
(15)
×sin
30
=2.869 m
b) Time of flight for projectile =
g
2μsinθ
9.8
2×15×sin30
=1.53 sec
c) Range =
sin2θ
×sin60
225
×
3
=19.74 m
hopefully it will work ☺️☺️
