Physics: Suppose you have three springs with force constants of k1 = k2 = k3 = 3.70 x 10^3 n/m. what is their effective force constant if one is hung from the other in series? you may assume the springs have negligible mass. the answer should be in n/m.

The effective force constant is 1233.33 N/m.

Explanation:

It is given that,

Force constant 1, $k_1=3.7\times 10^3\ N/m$

Force constant 2, $k_2=3.7\times 10^3\ N/m$

Force constant 3, $k_3=3.7\times 10^3\ N/m$

The effective force constant if one is hung from the other in series is given by :

$\dfrac{1}{K_{eff}}=\dfrac{1}{k_1}+\dfrac{1}{k_2}+\dfrac{1}{k_3}$

$\dfrac{1}{K_{eff}}=\dfrac{1}{3.7\times 10^3}+\dfrac{1}{3.7\times 10^3}+\dfrac{1}{3.7\times 10^3}$

$K_{eff}=1233.33\ N/m$

So, the effective force constant is 1233.33 N/m. Hence, this is the required solution.

According to the position vs time graph, the average velocity of the motorcycle is the change in position divided by the change in time. Also, note that the slope is linear and positive throughout the 5 hours, it doesn't change direction.

Therefore, we have
Avg velocity = change in direction/change in time
Avg velocity = (150km - 30km)/(5h - 0h)
Avg velocity = 24km/hr south.
