Stars are not really planets because they are far, far away from our solar system.
Hope this is helpful~
Answer:
they move in an orbit of a fixed size and also energy
Answer:
A =150

Momentum = (mass) x (speed) .
So 907,175 kg-m/s = (36,287 kg) x (speed)
Divide each side by (36,287 kg):
Speed = (907,175 kg-m/s) / (36,287 kg)
<em>Speed = 25 m/s</em>
That's the truck's <em>speed</em>. We can't do anything that involves the truck's <em>velocity,</em> because we don't know what direction the truck is moving.
Answer:
12 m/s
Explanation:
Given data
Mass m= 1500kg
intitial velocity u= 20m/s
force F= 6000N
time t= 2 seconds
Required
The final velocity v
From
Ft= mΔv
Ft= m(u-v)
substitute
6000*2= 1500(20-v)
solve for v
12000= 30000- 1500v
collect like terms
12000-30000= -1500v
-18000= -1500v
divide both sides by -1500v
v= 18000/1500
v=12 m/s
Hence the velccity is 12 m/s
