A : 7.8 grams per millilitre
B : 3×10^-2 kilograms/cm^3
the answer to this question is b
recall this kinematic equation:
this equation gives the acceleration of the object assuming it is constant (the velocity changes at a uniform rate).
a is the acceleration.
vi is the initial velocity.
vf is the final velocity.
δt is the amount of elapsed time.
vi = 0 m/s (the car starts at rest).
vf = 25 m/s.
δt = 10 s
substitute the terms in the equation with the given values and solve for a:
a =a = 2.5 m/s²
