- At an outdoor market, a bunch of bananas is set into oscillatory motion with an amplitude of 20.0 cm on a spring with a force constant of 16.0 N/m. It is observed that the maximum speed of the bunch of bananas is 43.0 cm/s. What is the weight of the bananas in newtons? NThe position of a 90 g oscillating mass is given by x(t)=A cos(10t−π/4)x(t)=A cos(10t−π/4), where ttt is in s and the amplitude A=4 cm. If necessary, round your answers to three significant figures. Determine The amplitude. The period. The spring constant. The phase constant.You have a metal spring of negligible mass that has spring constant k. The spring is supporting an object of mass m which is oscillating up and down with an angular frequency of w. What happens when a large steady current passes through the spring? O The oscillations gradually slow down until they come to a complete stop O The mass continues to oscillate with a reduced oscillation period O The mass continues to oscillate with an increased oscillation period O The mass continues to oscillate with the same oscillation period
