please answer all :)) 1. Two blocks are positioned on surfaces, each inclined at the same angle of 41.9 degrees with respect to the horizontal. The blocks are connected by a rope which rests on a frictionless pulley at the top of the inclines as shown, so the blocks can slide together. The mass of the black block is 3.95 kg, and the coefficient of kinetic friction for both blocks and inclines is 0.310. Assume static friction has been overcome and that everything can slide. What is must be the mass of the white block if both blocks are to slide to the RIGHT at a constant velocity? 2.

Simulate projectile motion with air resistance in PhysLab. A shuttlecock is launched from the ground with an initial speed of 34.0899 m/s at an angle of 5.2523 degrees with respect to the horizontal. The shuttlecock experiences air resistance with a drag coefficient of 0.106 in an environment where the air density is 0.3296 kg/m3. If the shuttlecock has a radius of 3.4 cm and a mass of 5.2 grams, what is the maximum height reached by the shuttlecock? Assume that the experiment is done near the surface of the earth.
Clarification: 1 h / 2 = 30 minutos The whole statement is in the picture. A block of mass ?1 = 250? is at rest on a plane that makes an angle ? = 30 ° about the horizontal. The coefficient of kinetic friction between the block and the plane is ?? = 0.100. This block is attached to a second block of mass ?2 = 200? that hangs freely from a rope that passes from a pulley without friction and with negligible mass. When the second block has fallen 30 cm, its speed is; a). 83 cm / s b). 160 cm / s If the rope breaks, after having traveled h / 2, calculate: The acceleration of each block. The time block 2 reaches the ground. The speed of block 2, an instant before it hits the ground and of block 1 when it reaches the end of the ramp.
Charlie is playing with his daughter Toney in the snow. She sits on a sled and asks him to slide her across a flat, horizontal field. Charlie has a choice of (a) pushing her from behind by applying a force downward on her shoulders at 30 below the horizontal (Fig. 5.18a) or (b) attaching a rope to the front of the sled and pulling with a force at 30 above the horizontal (Fig. 5.18b). Which would be easier for him and why?
