The modern theory of antimatter began in 1928, with a paper by Paul Dirac.
Answer:
number line
Explanation: hope this helps lol
Alright let's start this off with our basic equation!
Accerlation (
a) = ?
Initial velocity (
V1)= 60 mph = 88 ft/s (because we HAVE to convert mph to ft/s to match time)
Final velocity (
V2) = 0 ft/s because the car stops
Time (
t) = 4 seconds
a =
a =
a =
a = -22
Therefore, your acceleration is -22 ft/s² !! Hope this helped and was one of the branliest answers :')
It is very interesting step about Relative velocity. Actually, when you'll see the speed of fly in relation to ground, then it's speed would be 65 mph as train is traveling by that speed but if a person in on Train, then fly is at rest for him
Hope this helps!
