A bullet with a mass of 22 grams is shot into a hanging block with a mass of 3kg. The speed of the bullet is 760 m/s and causes a vertical displacement of 0.25 m. What is the maximum velocity of the block with a bullet lodged inside?

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

it's a b and

i believe the answer is electric potential.
