<span>We know that semimajor axis is a = (1/2)[(Re + hp)+(Re +ha)]
= 9.13*106 m
Re = radius of earth= 6380 km = 6380000 m
hp = height of perigee = 500 km = 500000 m
ha = height of apogee = 5000 km = 5000000 m
M = mass of the earth = 5.98*1024 kg
G = 6.67*10-11 Nm2/kg2
we know that time period of revolution of the spacecraft is
T= 2πa3/2/√GM
Then T = 2π*(9.13*106 )3/2/√6.67*10-11 *5.98*1024
= 8.67*103 sec

vp = spacecraft's speed at perigee
va=spacecraft's speed at apogee
Then vp /va =ra/rp = (Re+ha)/(Re +hp) = 6380+5000/6380+500
=1.654 </span><span>

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.

Compare the initial mass to the final mass.
Answer:
Non-metal
Explanation:
Diamond is a non metal because diamond is entirely made out of carbon and carbon is a non metal.
