A woman is walking, swinging her arms through a 30° angle every second. The length of each arm is 75 cm. Assuming that the arms move with constant speed during each swing, find the force that the blood vessel must exert on a 2-gram drop of blood from the end of the arm.

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

explanation:

suppose a rock in free fall is dropped off a cliff. after falling for 5 seconds, its speed would not be 100 m/s.
