1.You may use this way to get a bullet speed.
Suppose a bullet of mass
8.00 g is fired into a block of mass 2.50 Kg initially at rest at the edge of
a frictionless table of height 1.00m. The bullet remains in the block, and
after impact the block lands a distance 2.00 m from the bottom of the
table, Determine the initial speed of the bullet. (review perfectly inelastic
collision and projectile motion. V(bullet) = 1388m/s)
(2) A ball of mass m is attached to a string of length L. It is
being swung in a vertical circle with enough speed so that
the string remains taut throughout the ball's motion.
•
Find :
•
(1) TbTt, the difference between the tension in the string at the bottom relative to that
at the top of the circle in terms of m, g ( see your homework #7)
•
(2) find the centripetal acceleration difference at the bottom and the top
