The figure below shows a bar of mass m = 0.220 kg that can slide without friction on a pair of rails separated by a distance script l = 1.20 m and located on an inclined plane that makes an angle θ = 34.0° with respect to the ground. The resistance of the resistor is R = 1.20 Ω and a uniform magnetic field of magnitude B = 0.500 T is directed downward, perpendicular to the ground, over the entire region through which the bar moves. With what constant speed v does the bar slide along the rails?

The figure below shows a bar of
mass m = 0.240 kg that can slide without friction on a pair of
rails separated by a distance = 1.20 m and located on an inclined
plane that makes an angle θ = 29.0° with respect to the ground. The
resistance of the resistor is R = 2.20 Ω and a uniform magnetic
field of magnitude B = 0.500 T is directed downward, perpendicular
to the ground, over the entire region through...

A bar of mass m = 0.200 kg slide without friction on a pair of
rails separated by a distance at the length of 1.20 m. The pair of
rails was located on an inclined plane making an angle of 25
degrees with respect to the ground. The rails were connected by a
resistor at the top of the incline. The resistance of the resistor
is R= 1 Ohm, and a uniform magnetic field of magnitude B = 0.500 T...

A softball of mass 0.220 kg that is moving with a speed of 8.0
m/s (in the positive direction) collides head-on and elastically
with another ball initially at rest. Afterward the incoming
softball bounces backward with a speed of 6.4 m/s.
(a) Calculate the velocity of the target ball after the
collision.
(b) Calculate the mass of the target ball

As shown in the figure below, a box of mass
m = 68.0 kg
(initially at rest) is pushed a distance
d = 91.0 m
across a rough warehouse floor by an applied force of
FA = 226 N
directed at an angle of 30.0° below the horizontal. The
coefficient of kinetic friction between the floor and the box is
0.100. Determine the following. (For parts (a) through (d), give
your answer to the nearest multiple of 10.)

Figure 8-31 shows a ball with mass m ? 0.341 kg attached to the
end of a thin rod with length L ? 0.452 m and negligible mass. The
other end of the rod is pivoted so that the ball can move in a
vertical circle. The rod is held horizontally as shown and then
given enough of a downward push to cause the ball to swing down and
around and just reach the vertically up position, with zero speed...

The diagram below shows a block of mass m = 2.00 kg on a frictionless horizontal surface, as seen from above. Three forces of magnitudes F1 = 4.00 N, F 2 = 6.00 N, and F 3 = 8.00 N are applied to the block, initially at rest on the surface, at angles shown on the diagram. In this problem, you will determine the resultant (total) force vector from the combination of the three individual force vectors. All angles...

Block A in the figure below has mass 1.30 kg , and
block B has mass 2.85 kg . The blocks are forced together,
compressing a spring S between them; then the system is
released from rest on a level, frictionless surface. The spring,
which has negligible mass, is not fastened to either block and
drops to the surface after it has expanded. Block B
acquires a speed of 1.20 m/s .
