* Problem 11 - Free fall motion (20 points) You throw a ball vertically upward from the flat roof of a tall building. The ball leaves your hand at a point even with the roof railing, with an upward velocity of 12 m/s. On its way back down, it just misses the railing. Find (a) the position and velocity of the ball 1.5 s and 5 s after it leaves your hand; (b) the velocity of the ball when it...

3. (20 points) A block m = 5.00 kg is pushed up an inclined plane of angle 60.0°, as shown in Figure 4. There is friction between the surface of the block and plane. The coefficient of static friction is his = 0.400, and the coefficient of kinetic friction is pk = 0.300. (a) Find the minimum applied force F such that the block remains on the plane without moving. (b) If F = 60.0 N and the length of...

A brick is given an initial speed of 5 ft/s up an inclined plane at an angle of 30° from the horizontal. The coefficient of friction is u = V3/12. After 0.5 seconds, how far is the brick from its original position? You may take g= 32 ft/s”, sin 30º = 1/2, and cos 30º = V3/2.

Figure 4: Top view of force table. (3) Figure 5 is an inclined-plane system that will be stud- ied in the first part of this experiment. As labelled in the figure, the x (y) direction is parallel (perpendicular) to the inclined plane, and the gravitational acceleration is downward. If the hanging mass m is too small, the block mass M on the inclined plane slides down. When the hanging mass is gradually increased to a lower-bound value mi such that...
