6 A uniform disk of mass M = 750 g, radius r = to rotate about an axis going into the paper at point P. The disk is initially at rest. A cord is attached at one end to the rim of the disk and wraps around the rim. At time t =0 s a constant force of 1.05 N is applied to the free end of the cord causing the disk to rotate. 28 cm, is free What is the moment of inertia, I, of the disk? a. b. What is the angular acceleration of the disk? What is the angular velocity of the disk at t= 3.00 s?

A person is determined to travel to a distant star 30 ly away from the surface of earth. Calculate the velocity of his spaceship if it takes him 60 years to reach the star

Define the kinetic energy of an object with mass m moving with velocity v and give its units.

Please explain the steps to find the answer, which equation you are using and why you are using it. Thanks.

In outer space a constant force is applied to a 33.8 kg prove initially at rest. The probe no he s a distance of 103m in a 12s a..) what acceleration does this force produced express your answer in meters per deacons squared  b.) what is the magnitude of the force express your answer in Newton's

multiple choice question As the velocity of an inertial frame of reference increases with respect to a stationary observer, Einstein's theory of special relativity predicts that the length of an object, measured in the dimension parallel to the motion of the reference frame, will A decrease. B. remain unchanged. Jump to 1 2 3 4 5 6 7 8 9 10 increase. D. increase at first but start to decrease when the speed of the reference frame equals half the speed of light. E. decrease at first but start to increase when the speed of the reference frame equals half the speed of light.

how do I convert a Newton*meter/meter^2 to Newton/meter^2 I figured out that I divied by 1000 but I dont understand how the units cancle my actual numerical answer is  266240Nm/m^2 and the correct answer is 266.24 N/m^2

help please answer in text form with proper workings and explanation for each and every part and steps with concept and introduction no AI no copy paste remember answer must be in proper format with all working

QUESTION 3 - The following equation refers to v-pendulum experiment: T4 = (44 L ki g²)(8 m4L/g² )d, where : L: length of the string (2 meters). T: pendulum periodic time d: distance between rods k: pendulum constant g: gravitational acceleration Given that the slope of the graph (T4,d) = -14.2 s4/m, and y-intercept = 13.5 s4, Find the value for g: 9.81 m/s2 O Can't be defined a- 8.51 m/s2 a 10.5 m/s²

A mass ma = 2kg slides down slippery ramp, reaching a speed v = 10 m/s at the bottom. After reaching the level ground ma collides with mass mg = perfectly inelastic collision. 3kg at bottom, sticking together in a a.) What was the height of the ramp, assuming that m, started from rest? b.) How fast were the combined masses ma and mg moving after sticking together? c.) The combined mass runs into a spring, which brings it to a stop after being compressed 7 cm. What is the spring constant k ?
