This question is wrong because in momontum we will write acceleration instead of speed. suppose acceleration is 5m/s2 then
P= ma
then put values
Answer:
292.31 m/s
Explanation:
If Distance (d) = 190m
Time (t) = 1.3s
Speed of sound in air (v) =?
then
2d=vt
v=2d/t
v= 2×190/1.3
v=292.31 m/s
KE = 1/ 2 * 1252 * 144
as KE = 1/2 * m * v ^2
= 90144 J
I would say a because that is the only one that makes sense but I’m not 100% sure
