At t = 0, an 885-g mass at rest on the end of a horizontal spring (k= 184 N/m)is struck by a hammer which gives it an initial speed of 2.26 m/s. Determine (a) the period and frequency of the motion, (b) the amplitude, (c) the maximum acceleration, (d) the total energy, and (e) the kinetic energy when x =0.40A where A is the amplitude.
Multiply \({\bf{3}}{\bf{.079 \times 1}}{{\bf{0}}^{\bf{2}}}{\bf{ m}}\) by \({\bf{0}}{\bf{.068 \times 1}}{{\bf{0}}^{{\bf{ - 1}}}}{\bf{ m}}\),taking into account significant figures.

An energy-absorbing car bumper has a spring constant of \(410\;{\rm{kN/m}}\). Find the maximum compression of the bumper if the car, with mass \(1300\;{\rm{kg}}\), collides with a wall at a speed of \(2.0\;{\rm{m/s}}\) (approximately \(5\;{\rm{mi/h}}\)).
Write the following as full (decimal) numbers without prefixes on the units: (a) 286.6 mm, (b) 85 渭V(c) 760 mg, (d) 62.1 ps, (e) 22.5 nm, (f) 2.50 gigavolts.
