Sorry, the formula is a= force/mass= (3t^2-12t)/4 Why is there a 4?

Someone told me to use this formula but I don't understand why the 4 is in the first equation because the mass is 2 kg

A string is hanging from the rearview mirror of you car and a ball is at the end of this string. Suppose that you drive around a circular track at fixed speed. Which list below gives all the forces that act on the ball? A) tension and the force of gravity b) tension force of gravity and...

A 2.0 kg particle is moving along the x-axis to the left with a velocity of v= -6.0 m/s. Suddenly, between times t =0 and t = 4.0 x a net force = 3t^2 – 12t is applied to the particle, where F is in N and t is in s. Calculate the velocity of the particle at t=4.0 s. I am having trouble making...

Is momentum always conserved when total mechanical energy is conserved? My understanding is that this is false, but unsure.

Is it true or false that when a baseball player hits a home run, the baseball receives a greater impulse from the bat than the bat does from the ball? I think the answer is false because of the law of conservation of momentum.
