Most cars have hydraulic brakes. when a person pushes on the brake pedal, a force is applied to a small piston with a cross-sectional area of 1.8 cm2. by pascal's principle, the pressure is transmitted through the brake fluid to two larger pistons (each with an area of 8 cm2). the larger pistons push on the brake pads and the brake pads rub against the rotor (which stops the car). when a force of 7.6 n is applied by the brake pedal to the small piston, what force (in n) does each of the larger pistons apply to the rotor?

What is the major limitation to the light microscope?

The friction of the water on a boat produces an acceleration of -10. m/s2. if the boat is traveling at 30. m/s and the motor is shut off, how long it take the boat to slow down to 5.0 m/s?

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.
