A small block of mass M slides up the incline of angle A with an initial speed Vo in the position shown. The surface is rough with coefficient of kinetic friction u. The block moves a distance D up the ramp.
a) Where and in what ways do Newton's Laws apply?
b) where and in what way do energy methods apply?
In a game of basketball, a forward makes a bounce pass to the center. The ball is thrown with an initial speed of 4.3 at an angle of 24above the horizontal. It is released 0.75 above the floor.What horizontal distance does the ball cover before bounc..
An electron (charge q = -1.6x10-19 C and mass m = 9.1x10-31) moving at speed v enters a region where a uniform magnetic field B = 1.9 × 10-4 T bends the path of the electron into a semicircle with radius of r = 3.5 cm as shown. What is the speed o..
