An object undergoing simple harmonic motion takes 0.13 s to travel from one point of zero velocity to the next such point. The distance between those points is 41 cm. Calculate (a) the period, (b) the frequency, and (c) the amplitude of the motion.

the first american roller coaster was the mauch chunk switchback railway, built in the mountains of pennsylvania in the mid-1800s. the track, originally built to send coal to a railway, was reconfigured as a "scenic tour."

force tends to be low and long diustance masses are high

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
