If a ball is rolling down a 13m ramp that is 20 degrees above the ground, how fast is the ball going when it reaches the end of the ramp?

i would like to make dinner for my mom, dad, and sister

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s

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
