  • A block of unknown mass is attached to a spring with a spring constant of 6.50 N/m and undergoes simple harmonic motion with an amplitude of 10.0 cm. which occurs at x = −A = −0.200 m. If you are only interested in the peaks in the magnitude of the acceleration, they occur for x = ±A.
1. A 3.0kg mass undergoes an acceleration given by a = (2.0i + 5.0j) m s2. Find the resultant force F and its magnitude. [Ser4 5-7] Newton’s Second Law tells us that the resultant (net) force on a mass m is P F = ma. So here we find: Fnet = ma = (3.0kg)(2.0i+5.0j) m s2 = (6.0i+15.j)N The magnitude of the resultant force is Fnet = q (6.0N)2 ...
