Question

A spring with spring constant 16 N/m hangs from the ceiling. A ball is attached to the spring and allowed to come to rest. It is then pulled down 6.5 cm and released. The ball makes 20 oscillations in 24 s seconds. Part A What is its the mass of the ball? Express your answer to two significant figures and include the appropriate units.

Explanation / Answer

given;
k = 16 N/m
A = 0.065 m
= 20(2) = 40
t = 24 s


Part A.

= /t = 40/24

= 1.67

k = m²

16 = m(1.67)²

m = 0. 584 kg


Part B:

maximum speed is

V = A = 0.065(1.67)

V = 0.341 m/s
