need correct answer

Projectil A hot air balloon competition requires a balloonist to drop a ribbon onto a target on the ground. Initially the hot air balloon is 50 meters above the ground and 100 meters from the target. The wind is blowing the balloon at v 15 e to travel directly over the target. The ribbon is heavy enough that any effects of the air slowing meters/sec on a cours the vertical velocity of the ribbon are negligible. How long should the balloonist wait to drop the ribbon so that it willi hit the target? sec Submit

Only one question can be posted as per chegg guideines

1.

Time taken by the ballon to reach the ground

Y=Yo+Voyt-(1/2)gt2

=>0=50+0-(1/2)*9.8*t2

t=3.193

Horizontal distance travelled during this time

X=Voxt =3.193*15=47.9 m

Ballon must travel a distance before dropping from ballonist is

D=100-47.9=52.1 m

Therefore

twait =52.1/15 =3.474 s
