Please help me with these 2! QUESTION 4 The energy of an isolated system moving in a straight-line along the x-axis is given by the following equation: J E = (akg) v. + b X m If a = 6 and b = 6, what is the magnitude of the acceleration of this system (in m/s2)? QUESTION 4 The angular acceleration of an object as a function of time is given by the equation: rad 2 a(t)= a در 4...
The angular position of a rotating object is given by the equation e = a + bt + ct? where a, b, and care constants. Here a = 1.58 rad, b = 2.06 rad/s, and c = 2.92 rad/s2. (a) What is the position of the object at ti = 0 and t2 = 4.20 s? °1 = O rad 02 = O rad (b) What is the angular speed of the object at t1 = 0 and t2 =...
An object is being swirled in a circle at the end of a string. At time t = 0, the angular speed of the object is 0.6 rad/s. If the torque on the system produces an angular acceleration of 0.13 rad/s2, what is the angular speed after 25 rad of angular motion?
The angular position of a rotating object is given as a function of time by ? = 4t 3 - 3t, where ? is in radians and t is in seconds. What is its angular acceleration at t = 2 s? A None of the choices are correct. B 48 rad/s2 C 42 rad/s2 D 24 rad/s2 E 45 rad/s2

An object is moving at a constant speed around a circle. In which of these cases does the magnitude of the centripetal acceleration of the object increase the most? The radius of the circle doubles The object's speed doubles The object's speed is halved The radius of the circle is halved
An object of mass 0.2 kg is moving in a circle of radius 2 m with translational acceleration a = 5 m/s^2 . What will be the total Torque on the object?
Please answer the following question In Case A an object is moving straight downward with a constant speed of 9.80 m/s, while in Case B an object is moving straight downward with a constant acceleration of magnitude 9.80 m/s2. Which one of the following is true? a nonzero net external force acts on the object in neither case. a nonzero net external force acts on the object in Case B only. a nonzero net external force acts on the object...
Circle answers please An object with a mass of m = 5.5 kg is attached to the free end of a light string wrapped around a reel of radius R = 0.275 m and mass of M = 3.00 kg. The reel is a solid disk, free to rotate in a vertical plane about the horizontal axis passing through its center as shown in the figure below. The suspended object is released from rest 6.40 m above the floor. M...
