The force necessary to gain the velocity is 40 N.
The velocity gained by the object at the end of the second minute is 30 m/s.
<h3>Force of the object</h3>
F = mv/t
where;
- m is mass of the object = 200 kg
- v is velocity of the object = 60 m/s
- t is time of motion = 5 mins = 300 seconds
F = (200 x 60)/(300)
F = 40 N
<h3>Velocity of the object</h3>
F = mv/t
Ft = mv
v = Ft/m
where;
- m is mass = 600 kg
- F is force = 150 N
- t is time = 2 mins = 120 s
v = (150 x 120)/(600)
v = 30 m/s
Thus, the force necessary to gain the velocity is 40 N.
The velocity gained by the object at the end of the second minute is 30 m/s.

Answer:
B = A : 2
Explanation:
because is the opposite of A=2B
I'm not positive however my guess is this.
KE=(1/2)mv^2
KE=(1/2)(55)(121)
KE=3327.5m/s^2
You might not want to use this tho.
The speed of light (electromagnetic radiation) is equal to 299 792 458
m / s or 3x10^8 m/s in scientific notation.
So with this information, we could now look for the
distance. Solution:
Take note that μs means microseconds.
Speed of light * microseconds travelled * actual amount of microseconds
(3x10^8 m/s) (45.0 μs) (1x10^-6 s/μs) = 13,500 m.
