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:
Flexibility! :)
Explanation:
Agility: The ability to rapidly and accurately change the direction of the body. It is important in sports such as tennis which requires players to change direction quickly to hit the ball.
Flexibility: The muscles’ ability to move a joint through a full range of motion, and staying flexible is important to health and performance. As the body ages, the muscles, tendons, and ligaments stiffen, lose elasticity, and become less flexible.
Power: The ability to move the body parts swiftly while applying the maximum force of the muscles.
Body Composition: The combination of fat mass and fat-free mass, including bones, muscles, organs, and water.
Explanation:
The width of the central maximum is given by
W = 2 λ L / a
where W is the width of the central maximum
λ is the wavelength of the light used.
L is the distance between the aperture and screen
a is the width of the slit or aperture
So we can see that if any one quantity is varied by keeping others constant in the above formula , there would be a change in width of central maximum.
A because it is a formula for h*2
