WHEN THE Y COMPONENT OF VELOCITY EQUALS 160m/s WHAT IS THE X COMPONENT
A. 280m
B. 290m
C. 310m
D. 340m

Can u draw it ?

jiteshmeghwal9 · Answer

Let us find the time when the velocity of Y_component becomes 160 m/s.
$$v_y=u_y-g t$$$$160=200-10t$$$$t=4 \sec$$As we know x-component of velocity will remain same throughout the projectile motion. Therefore,$$\Large{X=u_xt}$$u_x=80 m/s
t=4 sec.
solve it
