Answer:
Explanation:
m = Mass of ball = 150 g
= Angle of kick = 
= Displacement of ball in x direction = 12 m
Range of projectile is given by
The velocity of the ball instantly after the man kicks the ball is
Impulse is given by
The impulse of his foot on the ball is .
Answer:
340 m/s
Solution:
As per the question;
Time, t = 3.0 s
Total distance moved by the ship, d = 10,500 km
The increase in speed, v = 340 m/s
Now,
To calculate the U.S.S Burger's change in speed, 
:
The final velocity is given by:
(1)
where
Also, the change in velocity is given by:
(2)
Now, from eqn (1) and (2):
I think it would be Fusing of 2 or more small atoms into a larger one
Option B is correct. If an incident light ray hits a flat, smooth object at 28°. It will reflect off at an angle of 28°.
<h3>What is the law of reflection?</h3>
The law of reflection specifies that upon reflection from a downy surface, the slope of the reflected ray is similar to the slope of the incident ray.
The reflected ray is consistently in the plane determined by the incident ray and perpendicular to the surface at the point of reference of the incident ray.
When the light rays descend on the smooth surface, the angle of reflection is similar to the angle of incidence, also the incident ray, the reflected ray, and the normal to the surface all lie in a similar plane.
If an incident light ray hits a flat, smooth object at 28 degrees, it will reflect off at an angle of 28°.
Hence, option B is correct
