Question

A body is projected with velocity of 24 making an angle 30 with the horizontal.The vertical component of its velocity after 2 sec

Answer 1

the vertical component of the velocity is defined by sine of the angle,

therefore,

sin30 = 1/2

and by applying v=u+at

v= 24+(-9.8)*2
v= 4.4

vertical component would be 4.4*(1/2) = 2.2 m/s

Enjoy

Answer 2

horizontal component formula is u
$u \cos(?)$
u=24
angle=30
24×cos(30)
24×√3/2
=20.7
after 2 sec
v=1/2at
$v = 1 \div 2at {?}^{2}$
v=1/2×9.8×4
=19.4
v=19.4
