A 5 n force is applied to a 3 kg ball to change its velocity from +9 m/s to +3 m/s. the time for the collision is _____ seconds.
The time for the collision is 3.6S.
What is collision?The collision is an encounter between particles resulting in exchange or transformation of energy.
According to the question,
Force,
F = 5 N
Mass,
m = 3 kg
Velocity,
v₁ = 9 m/s and v₂ = 3 m/s
As we know,
F=m*(v/t)
so,
5=3*(9-3/t)
T=3*6/5
T=18/5

Answer:
What is the degrees of freedom when the sample size is 20?
19
For example, if we have a sample of size n = 20 items, then we calculate the degrees of freedom as df = n – 1 = 20 – 1 = 19 and we write the distribution as T ~ t19.
Explanation:
The degrees of freedom can be used to test a hypothesis about the mean.
What is degrees of freedom?Degrees of freedom refers to the maximum number of logically independent values that have the freedom to vary, in the data sample.
Given, the sample size is 20, then degree of freedom will be
The degrees of freedom represented as
dof = n – 1
dof = 20 – 1
dof = 19
