A 0.0200-kg bolt moves with SHM that has an amplitude of 0.240 m and a period of 1.500 s. The displacement of the bolt is + 0.240 m when t = 0. Compute (a) the displacement of the bolt when t = 0.500 s; (b) the magnitude and direction of the force acting on the bolt when t = 0.500 s; (c) the minimum time required for the bolt to move from its initial position to the point where x = - 0.180 m; (d) the speed of the bolt when x = - 0.180 m.
MATH 2450 WEEK 7 Strategy On a close domain, look for all critical points inside the domain. Look for the boundary points then compare. Look for all critical points inside the domain: F = 0 x Fy= 0 Look for all critical points on the boundary g’(t) = 0 Look at the boundary points of the boundary EX.
