Answer:
v = 5.88 10⁷ m / s
Explanation:
For this exercise we use the relation
E = m c²
also indicate that all energy is converted into kinetic energy
E = K = ½ (M-2m) v²
where m is the mass of antimatter and M is the mass of the ship's mass. Factor two is due to the fact that equal amounts of matter and antimatter must be combined
we substitute
m c² = ½ (M-2m) v²
v² =
let's calculate
v =
v =
v = 5.88 10⁷ m / s
Answer:
Mercury has the lowest melting point.
A - the amount of time needed to travel the distance
The formula for speed is distance/time and the unit is m/s. Therefore you divide the distance travelled by the time it took to travel it.
Answer:
b) 105220.8 m
c) 65.38 miles
d) Kenneth's home
Explanation:
Velocity of Sarah = 31 m/s east
Velocity of Kenneth = 65 mph = 65×(1609.34/3600) m/s west
Time in seconds = 29.2×60 = 1752 s
Displacement = Velocity × time
Displacement of Sarah = 31×1752 = 54312 m
Displacement of Kenneth = 65×(1609.34/3600)×1752 = 50908.8 m
b) So, distance between their homes in meters is 54312 m + 50908.8 m = 105220.8 m
c) Converting to miles
Their homes are 65.38 miles apart
d) They met closer to Kenneth's house (50908.8 m)
