1. w = 2*pi/ T = 2*3.14/0.6 = 10.47 rad/s
a) v = rw = 1.25* 10.47 = 13.08 m/s
b) a = r w^2 = 1.25* 10.47^2 = 137.03 m/s^2
c) tension = ma = 0.2* 137.03 = 27.4 N
==========
2.
a) resultant force acting = 6*1.5 = 9 N
b) magnitude of force = 6 ( 15/6 - 1.5) = 6 N

Comment in case any doubt.. Goodluck
Please do all questions and show work. 1. (2 points) A 200 g mass attached to a light spring oscillates on a frictionless, horizontal table. The mass is pulled 8 cm and released. A student finds that 12 oscillations takes 18 seconds. (a) What is the spring constant? (b) What is the maximum speed of the mass? 2. (3 points) The position of an object connected to a spring varies with time according to the expression x = (7.5 cm)cos...
please explain the answers. 8) I was a scout when I was a young boy. Each year the scouts would participate in the pine wood derby (look up pine wood derby if don't know what that is). In the pine would derby you build a toy car out of a block of pine wood. Each scout then races their car in a competition, by letting their car go down a ramp. The rules of the pine wood derby dictate that...
13. A partile is in simple harmonic motion along the x axis. The amplitude of the motion is When it is at , its kinetic energy is K 5J and its potential energy (measured with 0 isU-3J. When it is at r -12 , the kinctic and potential energies are 0 at x CK-8J and U 0 K-0J and U-S sot Sure 14. The system of pulleys and a hanging weight shown to the right is in equilibrium due to...
The answers are 23 (D), 28 (A), 30 (A), and 31 (D). Please show the step by step solution. I need to understand HOW to do these problems so please only answer if you can help. Thank you in advance! 15. (N) 23). A 5 kg object that moves along the x-axis is acted upon by a net force that varies with position as shown in the figure at right. The kinetic energy of the particle at x= -2 m...
1. A pole is held vertically by attaching wires at a height of 13.4 m above the ground. The other end of each wire is anchored in the ground at a distance of 9.54 m from the base of the pole. The pole makes a right angle with the ground. What is the length of each wire? 2. A bug crawls 2.25 m along the base of a wall. Upon reaching a corner, the bug's direction of travel changes from...
