A jogger accelerates from rest to 2.9 m/s in 2.3 s. A car accelerates from 36.0 to 42.0 m/s also in 2.3 s. (a) Find the acceleration (magnitude only) of the jogger. m/s2 (b) Determine the acceleration (magnitude only) of the car. m/s2 (c) Does the car travel farther than the jogger during the 2.3 s

A2.00-m long piano wire with a mass per unit length of 12.0 g/m is under a tension of 8.00 kn. what is the frequency of the fundamental mode of vibration of this wire?

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].

Ahanging spring stretches by 35.0 cm when an object of mass 450 g is hung on it at rest. in this situation, we define its position as x = 0. the object is pulled down an additional 18.0 cm and released from rest to oscillate without friction. what is its position x at a moment 84.4 s later? express your answer in cm.
