Diagram (b) is a free-body force diagram for the cupboard. *State the magnitude of force Y.

*Explain why forces X and P must have equal magnitude.

*Calculate the moment of the weight of the cupboard about a point A.
Moment=?

*Calculate the value of force X when h=0.60 m.
Force X=?

*In principle the fixing screws could be positioned anywhere between point A and the top of the
cupboard. Sketch a graph to show how the size of force X would depend on h for values of h from
zero up to 0.60 m.

For general projectile motion, when the projectile is at the highest point of its trajectory, its acceleration is zero? a)the horizontal and vertical components of its velocity are zero. b) its velocity is perpendicular to the acceleration. c)the horizontal component of its velocity is zero. d)its velocity and acceleration are both zero.

Abasketball star covers 2.65 m horizontally in a jump to dunk the ball. his motion through space can be modeled precisely as that of a particle at his center of mass. his center of mass is at elevation 1.02 m when he leaves the floor. it reaches a maximum height of 1.90 m above the floor and is at elevation 0.910 m when he touches down again. (a) determine his time of flight (his "hang time"). (b) determine his horizontal velocity at the instant of takeoff. (c) determine his vertical velocity at the instant of takeoff. (d) determine his takeoff angle. (e) for comparison, determine the hang time of a whitetail deer making a jump with center-of-mass elevations yi = 1.20 m, ymax = 2.45 m, and yf = 0.750 m.
