Passes the the law then through the people where it is followed
Answer:
-26 m/s (backward)
Explanation:
We can solve this problem by using the law of conservation of momentum.
In fact, the total momentum momentum of the cannon + ball system must be conserved before and after the explosion.
Before the explosion, they are both at rest, so the total momentum is zero:
p = 0
After the explosion, the total momentum is:

where
M = 1.5 kg is the mass of the cannon
m = 0.52 kg is the mass of the ball
v = +75 m/s is the velocity of the ball
V is the velocity of the cannon
Since the momentum is conserved, we can equate the two expressions:

And solving, we find V:

where the negative sign means the direction is opposite to that of the ball.

Answer:
linear perspective
Explanation:
Railroad tracks appear to converge due to our field of view. When an object is far away it seems smaller that means there is angle that subtends from our line of sight this results in the illusion of railroad tracks converging.
Railroad tracks converging activates the linear perspective of our vision. Linear perspective is a technique used to convey a sense of depth in two dimensional representation of an object. The lines at an angle give us a sense of depth otherwise straight lines will not be able to convey depth.
Answer:
Tension, Ft = 79.91 N
Explanation:
The tension in the string is the resultant force that exists in the string due to the centripetal effect of the swinging ball.
From conservation laws, the tension in the string will be equals to the centripetal force acting on the string.
The tension in a string can be obtained using the formula:

where v = linear velocity of the metal ball which equals to the angular velocity of the ball X the radius of the ball.
The radius of the ball is given as 72 cm = 0.72m and the angular velocity = 1.02 rad/second.
Therefore, linear velocity, 
The tension in the string will now be equals to
