Answer:
500km/h
Explanation:
I don't know what units you need the answer in, but if the units were to stay the same, then that's the answer^.
The speed of the target with the bullet lodged in it is 5.6 m/s.
<h3>What is speed?</h3>
This is the rate of change of distance.
To calculate the speed of the target and the bullet lodged, we use the formula below.
Formula:
- V = mu/(m+M)............. Equation 1
Where:
- V = Speed of the target and the bullet
- m = mass of the bullet
- M = mass of the target
- u = Initial speed of the target
From the question,
Given:
- m = 0.04 kg
- u = 1400 m/s
- M = 9.96 kg
Substitute these values into equation 1
- V = (0.04×1400)/(0.04+9.96)
- V = 56/10
- V = 5.6 m/s
Hence, the speed of the target with the bullet lodged in it is 5.6 m/s.

Answer: C
The gravity acceleration is in the same direction as the force of gravity, and thus toward the center of the earth.
Explanation:
All celestial bodies in our solar system experience forces between each other. On earth, the localized gravitational force in the earth's atmosphere is directed toward the center of the earth. It's magnitude is
32.174 ft/s² in English units,
9.807 m/s² in SI units.
All objects that have mass are subject to the earth's gravitational acceleration. The product of mass and the earth's gravitational acceleration defines the weight of an object as its gravitational force.
(25m north) + (10m south) = 15m north
(10m east) + (5m west) = 5m east
So the bee is now 15m north and 5m east of the hive.
The gravitational force between earth and moon will increase.
by F = GMm/r^2
F is inversely proportional to r^2
when r decrease, F will increase.
