Question

A quarterback throws a football at 40 km/hr to a receiver 50 yd away. How much time does it take the ball to reach the receiver? Would 40 km/hr be a acceleration or a velocity?

Answer 1

velocity. is the answer.
if it was acceleration, it would be written as 40km/hr^2

Answer 2

How would you know that it's acceleration
?

Answer 3

for time, use distance= velocity x time. thus,
distance/velocity= time, 50 yard = 0.036576 km
0.036km/40km/hr = 0.0009 hour. if u wish, u can convert to seconds

Answer 4

accelerations are usually written as km/hr square

Answer 5

Ok so what would velocity usually be? And thank you by the way

Answer 6

velocity would be m/sec, km/hr, mile/hour with out square at the bottom

Answer 7

Wait I'm confused. What do you mean without square?

Answer 8

means if its velocity, the time would not be squared while acceleration's time is usually squared.

Answer 9

Okay Okay I see , Thank you. You were a great help . I have a test tomorrow and I think this really helped :)

Answer 10

ure welcome :)
