A pendulum, consisting of a ball of mass m on a light string of length 1.00 m, is swung back to a 45° angle and released from rest. The ball swings down and, at its lowest point, collides with a block of mass 2m that is on a frictionless horizontal surface. After the collision, the block slides 1.00 m across the frictionless surface and an additional 0.290 m, before coming to rest, across a horizontal surface where the coefficient of friction between the block and the surface is 0.120. Useg = 9.80 m/s2.
(a) What is the block's speed after the collision?
(m/s)
(b) What is the velocity of the ball immediately after the collision? Use a plus sign if the velocity is in the same direction as the velocity of the ball just before the collision, and a negative sign if the velocity is in the opposite direction as the velocity of the ball just before the collision.
A car traveling at 24 m/s runs out of gas while traveling up a 9 degree slope. How far will it coast before starting to roll back down.
An AC adapter for a telephone-answering unit uses a transformer to reduce the line voltage of 120 V (rms) to a voltage of 10.0 V. What is the rms power delivered to the transformer
Assume you wish to send a 200 bytes long message from your equipment to a friend's machine via four intermediate nodes. You are needed to use a header size of 5 bytes per packet.
implies a serious limit to such detection. (Note also that the uncertainty is greater if there is an uncertainty in the propagation speeds of the S- and P-waves).
The function y(x, t) = (25.0 cm) cos(?x - 20?t), with x in meters and t in seconds, describes a wave on a taut string. What is the transverse speed for a point on the string at an instant when that point has the displacement y = +22.0 cm?
