Can you please give me the whole solution for this question! Thanks 2. According to Newton's Law of Universal Gravitation, the gravitational force on an object of mass m that has been projected vertically upward from Earth's surface is F( is the objer s distan boe he urfac at time t, Ris Earth's radius, ngR (x+R)2 and g is the acceleration due to gravity. Also, by Newton's Second law, mgR2 (x +R)2 dv F = mal = m dt =...

2 I= (Equation 1) 2 For rotational motion, Newton's second law (see Equation 2) can be adopted to describe the relationship between the applied torque, T and angular acceleration, a. T = la (Equation 2) Note that for rotational motion with constant angular acceleration, the angular displacement of a rotating object can be obtained from Equation 3: 0 = 0,1 + tar (Equation 3) Task: Derive (Equation 1) and (Equation 3)
1. According to Hooke's law, the force exerted by a spring is proportional to the amount of stretch (or change in length Ax) and is given by F = -KAX, where the minus sign indicates it is a restoring force. If a force of 120 N acts on a mass 250 g attached to a spring of constant K = 54.55 x 103 N/m. Calculate the following: The change in length Ax The angular frequency (w) The frequency (f) The...

In a hurry to digest this . Tks for the help (thumb up) 2. A mass of m kilograms (kg) is mounted on top of a vertical spring. The spring is L metres long when disengaged and the end not attached to the mass is fixed to the ground. The mass moves vertically up and down, acted on by gravity, the restoring force T of the spring and the damping force R due to friction: see the diagram below The...
