F=ma
a=F/m
a=2000/1000
a=2 m/s^2
When looking for distance you multiply speed by time
So 15 x 2 = 30
30 is the distance between his house and school
Answer:
The toy car. An object that isn't moving has no momentum
Explanation:
Answer:
895522 times faster.
Explanation:
From the question given above, the following data were obtained:
Speed of sound in air (v) = 335 m/s
Speed of light in air (c) = 3×10⁸ m/s
How many times faster =.?
To obtain how many times faster light travels in air than sound, do the following
c : v => 3×10⁸ : 335
c/v = 3×10⁸ / 335
c/v = 895522
Cross multiply
c = 895522 × v
From the illustrations made above, we can see that the speed of the light in air (c) is 895522 times the speed of sound in air.
Thus, light travels 895522 times faster than sound in air.
