Does anybody know how to do this?
Three objects are connected by light strings. The stringconnecting the 4.00kg object and 5.00 object passes over a light friction less pulley. Determine the acceleration of each object andthe tension of the two strings.

b) During the sliding, what are the ball's linear accelerationand
c) angular acceleration?
d) How long does the ball slide?
e) How far does the ball slide?

A smallspring is compressed when a soap dispenser's pump is pushed. The spring has a potential energy of 0.0025 J when it is compressed by 0.54 cm.
(a) What is the force constant of the spring?in kN/m
(b) What compression is required for the spring potential energy toequal 0.0080 J?
An electron is accelerated horizontally from rest in atelevision picture tube by a potential difference of 5710 V. Itthen passes between two horizontal plates 6.66 cm long and 1.29 cmapart that have a potential difference of 256 V (see figure below).
At what angle q will the electron betraveling after it passes between the plates?
(1999) As shown above, a uniform disk is mounted to an axle and isfree to rotate without friction. A thin uniform rod is rigidlyattached to the disk so that it will rotate with the disk. A blockis attached to the end of the rod. Properties of the disk, rod, andblock are as follows.
Disk: mass = 3m, radius = R, moment of inertia about centerID = 3/2
Rod: mass = m, length = 2R, moment of inertia about one endIR = 4/3
Block: mass = 2m
The system is held in equilibrium with the rod at an angle0to the vertical, as shown above, by a horizontal string ofnegligible mass with one end attached to the disk and the other toa wall. Take m = 37 kg, R =0.63 m, and
(a) Determine the tension in the string.
(b) Determine the following for the instant immediately after thestring is cut.
An 8.0 m, 200 N uniform ladder rests against a smooth wall.The coefficient of static friction between the ladder and theground is 0.60, and the ladder makes a
i keep getting 2.85 m but on this site, the answer is 6.15.
am i doing something wrong with the calculations?
can anyone please elaborate this to me? I'd greatly appreciate it.
A 1300 kg car is constructed on a frame that is is in turn supported by four springs. each spring has aspring constant of . Two passengers in the car have a combined mass of 160 kg. What is the frequency of free vibration of the car when it is driven ovr arough road?
How long does it take the car to execute three complete oscillations?
