Two constant forces act on an object of mass m = 5.60 kg object moving in the xy plane as shown in the figure below. force f1 is 27.5 n at 35.0°, and force f2 is 41.0 n at 150°. at time t = 0, the object is at the origin and has velocity (4.70i + 2.55j) m/s 150° 35.0 (a) express the two forces in unit-vector notation (b) find the total force exerted on the object. (c) find the object's acceleration m/s now, consider the instant t = 3.00 s (d) find the object's velocity m/s (e) find its position (f) find its kinetic energy from ½mvf2 (g) find its kinetic energy from ½mvi2 σf·

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].

The sun’s mass is 2.0×10^ 30 kg, its radius is 7.0×10 5 km, and it has a rotational period of approximately 28 days. if the sun should collapse into a white dwarf of radius 3.5×10 3 km, what would its period be if no mass were ejected and a sphere of uniform density can model the sun both before and after?
