A mason is shot with a constant speed of 7.5 x 10²m/sinto a region, when an electric field produces acceleration on the mason of magnitude 1.5 x 1025 ms-2 directed opposite to the velocity. Find the time taken (b) the distance covered by the mason before coming to rest and (c) the time for which it remains at rest.
Answers
Answer:
Distance, d = 0.1 m
It is given that,
Initial velocity of meson,
Finally, the meson is coming to rest v = 0
Acceleration of the meson, (opposite to initial velocity)
Using third equation of motion as :
s is the distance the meson travelled before coming to rest.
So,
s = 0.1 m
The meson will cover the distance of 0.1 m before coming to rest. Hence, this is the required solution.

b. The man stands still while he talks on his cell phone at the middle of the sidewalk, then
walks toward the house at a constant rate trying to get better cell reception. He comes to
a sudden stop when the coverage is good (about a meter before the house) and stands
still to finish his conversation.
c.The man starts close to the house, stands still for a little while, then walks toward the

A cannonball is fired from a cliff that is 50 meters above the ground. The cannonball is fired horizontally with a speed of 120 meters per second.
Calculate the horizontal distance that the cannonball will travel.
Answers
The horizontal distance that the cannonball will travel is 383.33m
In order to find the horizontal distance, we will use the formula for calculating the range expressed as:
[tex]R = u\sqrt{\frac{2H}{g} }[/tex] where:
u is the velocity
H is the height
g is the acceleration due to gravity
[tex]R = 120\sqrt{\frac{2(50)}{9.8} }\\R = 120\sqrt{\frac{100}{9.8} } \\R=120\times 3.1943\\R=383.33m[/tex]
Hence the horizontal distance that the cannonball will travel is 383.33m

How does that motion change for the object if the forces on the object are unbalanced?
Answers
When the forces on the object are unbalanced, the object will move in the direction of the greater force.
What is Newton's first law of motion?Newton's first law of motion states that an object at rest or uniform motion in a straight line will continue in that path unless acted upon by an external force and the object will tend to move in the direction of the applied force.
What is Newton's second law of motion?Newton's second law of motion states that the force applied to a body is directly proportional to the acceleration of the body.
F = ma
Unbalanced forces on a bodyIf the net force acting on a body is greater than zero, the body will tend to move in the direction of the greater force.
Thus, when the forces on the object are unbalanced, the object will move in the direction of the greater force.

Which line on the graph represents the greatest positive acceleration?
D
A
B
C
Answers
Answer:
I think it's B, if that's wrong I apologize. You might want to do more research on it and find the correct answer if you can, if it's right then you could like my comment, so others know if not give it 1 star, keep it low lol.
Explanation:
The line that represents the greatest positive acceleration is A.
In a velocity-time graph, the slope of the line represents the acceleration. The greater the slope, the greater the acceleration. Line A has the steepest slope, so it represents the greatest positive acceleration.
Line B has a positive slope, but it is not as steep as line A. Line C has a negative slope, which means it represents negative acceleration, or deceleration. Line D is a horizontal line, which means it represents a constant velocity, or zero acceleration.
Therefore, the line that represents the greatest positive acceleration is A.
