Answer:
I think the most you need would be 4or 5 to be bring it to a solid D but it really depends on what percent of the grade you have like if it's a 7% then it's going to take a little bit more than that

Step-by-step explanation:
The velocity of a particle when it moves on a straight line along the x-axis will be V= 42 m/s
<h3>What is velocity?</h3>
Velocity is defined as the ratio of the distance moved by the object in a particular time. The velocity is a vector quantity so it needs both the magnitude and the direction.
Here we have a displacement function:-
F(t)=3t⁴-5t³+6t-7
So to find out the velocity we will differentiate the above equation with respect to t.
d(F(t)/dt=12t³-15t²+6
V=12t³-15t²+6
Put the value of t=2 seconds
V=12x(2x2x2)-15x(2x2)+6
V=42 meters per second
Hence the velocity of a particle when it moves on a straight line along the x-axis will be V= 42 m/s
