Explanation:
Below is an attachment containing the solution.
-- The spaceship's AVERAGE speed during the acceleration is
(1/2) (58 m/s + 153 m/s))
= (1/2) (211 m/s)
= 105.5 m/s .
In 12 seconds at an average speed of 105.5 m/s,
the ship covers
(105.5 m/s) (12 sec) = 1,266 meters .
Answer:
Binding energy
Explanation:
The energy required to bind the nucleus is called binding energy.
Binding energy is equal to the product of mass defect and square of velocity of light.
Mass defect is the difference of mass of neucleons and the mass of atom.
Answer:
(a) 10 s
(b) 30 m/s
(c) 150 m
Explanation:
The motorist's position at time t is:
x = 15t
The officer's position at time t is:
x = ½ (3) t² = 1.5 t²
(a) When they have the same position, the time is:
15t = 1.5 t²
t = 0 or 10 s
(b) The officer's speed is:
v = 3t
v = 30 m/s
(c) The position is:
x = 15t = 150 m
