In trajectory, acceleration vector is not the same with the velocity vector but it depends on the change in velocity. The acceleration path is perpendicular to the velocity vector path. The Correct answers are:
a.) D
b.) B
c.) C
d.) A
A Vector is a quantity that has both magnitude and direction.
Given that a ball is fired from a cannon at point 1 and follows the trajectory shown in the figure.
a.) The vector best represents the ball's velocity at position 2 is D
b.) The vector best represents the ball's acceleration at point 2 is B
c.) Which vector best represents the ball's velocity at position 3 = C
d.) Which vector best represents the ball's acceleration at point = A
In trajectory, acceleration vector is not the same with the velocity vector but depends on the change in velocity. The acceleration path is perpendicular to the velocity vector path.
At point 3, since the ball path is parabolic, the velocity at that point is not equal to zero but will tend to take a horizontal path.

Answer: The kinetic energy is 300 joules
Explanation:
The question can be translated to:
The kinetic energy of a mass of 6kg that has a velocity of 10m/s:
Now, the kinetic energy can be written as:
k = (1/2)*m*v^2
where m is the mass and v is the velocity, we can replace the values:
k = (1/2)*6kg*(10m/s)^2 = 300 j
The kinetic energy is 300 joules
