A ball moving horizontally across my desk rolls off at a velocity of 3.3 m/s. Assuming my desk is a height of 0.81 m, how long w
ill the ball be in the air?
Answer in units of seconds. Assume acceleration due to gravity is -9.81 m/s^2

Answer:
girl what- I can't answer this but I need points so I'ma just put this random lol sorry tho . ask the tutor

Wavelength =v/f therefore wavelength= (340m/s)/(490Hz)= .694m
HOPE THIS HELPS! THANK YOU!
I’m pretty sure it’s B
B: If an object has mass, it has gravity.
This is what e=mc² means.
So rest energy is RH side of equation that is its mass times speed of light squared.
Answer:
245 m
Explanation:
v = at + v₀
50.0 m/s = a (9.8 s) + 0 m/s
a = 5.10 m/s²
x = x₀ + v₀ t + ½ at²
x = 0 m + (0 m/s) (9.8 s) + ½ (5.10 m/s²) (9.8 s)²
x = 245 m
C.
Thanks me later, that's my answer.
