Quinn launches two projectiles, x and y, at two different speeds. which best compares the motion of the projectiles? the horizontal velocity of projectile x is changing, and the vertical velocity of projectile y is constant. the vertical velocity of projectile y is changing, and the horizontal velocity of projectile x is constant. the horizontal acceleration of projectile x is –9.8 m/s2, and the vertical acceleration of projectile y is 0 m/s2. the horizontal acceleration of projectile y is –9.8 m/s2, and the vertical acceleration of projectile y is 0 m/s2.

yo yo yo its papaguy in the house lol

okay, ima .

um it shows links to uh so kinda microsoft website is that were ima go or no? ?

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min

0.93xc=0.93x3x10^8m/s
