An air-track glider attached to a spring oscillates between the 13.0 cm mark and the 65.0 cm mark on the track. The glider completes 14.0 oscillations in 35.0 s . What are the (a) period, (b) frequency, (c) amplitude, and (d) maximum speed of the glider?

Time period = 2.5 sec

Frequency = 0.4 Hz

Amplitude =  0.26 m

Maximum speed = 0.65

Explanation:

No. of oscillations = 14

Time = 35 sec

(a). Time period of oscillation

T = 2.5 sec

This is the time period.

(b). Frequency

f = 0.4 Hz

This is the  frequency.

(c). Oscillation from one side to another side is 65 - 13 = 52 cm = 0.52 m

Hence amplitude

A = 0.26 m

This is the amplitude.

(d). The maximum speed

2 × 3.14 × 0.4 × 0.26

0.65

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
