8.30 Asteroid Collision. Two asteroids of equal mass in the aster-
oid belt between Mars and Jupiter collide with a glancing blow. Asteroid
A, which was initially traveling at 40.0 m/s, is deflected 30.0° from its
original direction, while asteroid B, which was initially at rest, travels at
45.0° to the original direction of A (Fig. E8.30). (a) Find the speed of
each asteroid after the collision. (b) What fraction of the original kinetic
energy of asteroid A dissipates during this collision?

The initial velocities of A and B are given in Fig. P8.69. All three spheres arrive at the origin at the same time and stick together. (a) What must the x- and y-components of the initial velocity of C be if all three objects are to end up moving at 0.50 m/s in the +x-direction after the col- lision? (b) If C has the velocity found in part (a), what is the change in the kinetic energy of the system of three spheres as a result of the collision?

Just before impact, the ball is traveling horizontally to the right at 40.0 m/s; when it leaves the bat, the ball is traveling to the left at an angle of 30° above horizontal with a speed of 52.0 m/s. If the ball and bat are in contact for 1.75 ms, find the horizontal and vertical components of the average force on the ball.arrow_forwardL1=5.2m L2=0.5m L3=1.7m L4=0.6m L5=0.5m L6=0.5m V2=5.4m/sarrow_forward

The coefficient of kinetic friction is 0.20. The attached string is parallel to the incline and passes over a massless, frictionless pulley at the top.

What is the acceleration of Block B in m/s? show all steps pleasearrow_forwardWhen current is flowing through the coil, the direction of the torque can be thought of in two ways. Either as the result of the forces on current carrying wires, or as a magnetic dipole moment trying to line up with an external field (e.g. like a compass). Note: the magnetic moment of a coil points in the direction of the coil's magnetic field at the center of the coil. d) Forces: We can consider the left-most piece of the loop (labeled ○) as a short segment of straight wire carrying current directly out of the page at us. Similarly, we can consider the right-most piece of the loop (labeled ) as a short segment straight wire carrying current directly into the page, away from us. Add to the picture below the two forces due to the external magnetic field acting on these two segments. Then describe how these two forces give a torque and determine if the torque acts to rotate the loop clockwise or counterclockwise according to this picture? Barrow_forward
