Four forces act on a 10-kg mass in the force diagram below: a) Label the force diagram to the right with the correct symbol for each force arrow or vector. b) What is the acceleration of this 10-kg mass above?

The data below is from a student who walked slowly up the stairs, walked quickly up the stairs, and ran up the stairs. Table 1 Mass of Student 55 kg Height of Stairs 2.8 m Force due to Gravity     Calculations 1 Calculate the force due to gravity acting on the student. (Reminder: F = m*a; acceleration due to gravity = 9.8 m/s/s). Show your work below and record the value you get in Data Table 1.

A 0.10-kg ball is placed in a shallow wedge with an opening angle of 150°, as shown in(Figure 1). Figure Contact force 1 mg Contact force 2 1 of 1 ▼ For each contact point between the wedge and the ball, determine the force exerted on the ball. Assume the system is frictionless.
