A bow is launching an arrow. The extension of the thread before launch is 20 cm and the elastic constant is 50 N/m. The mass of the arrow is 20 g. The initial speed is zero. Find the speed when the extension was 10 cm. Given:
Si:
Question:
Formula:
Solve:

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

amplitude

hope this
