What is the mass of a baseball that has a kinetic energy of 100 J and is traveling at 5 m/s?

Answers

The formula of the kinetic energy is:
K.E = $(1)/(2)$ mv²

The given are
K.E = 100 J
v = 5 m/s

Plug them in:

100 = $(1)/(2)$ m × (5)²
100 = $(1)/(2)$ m × 25
100 = 12.5m
Divide by 12.5 on either sides to isolate m

$(100)/(12.5)$ = $(12.5m)/(12.5)$
12.5 and 12.5 cancels out
8 kg = m
The mass of the baseball that has a kinetic energy of 100 J and speed of 5 m/s is 8 kg

Answer:

mass = 8 kg.

Step-by-step explanation:

Given : kinetic energy of 100 J and is traveling at 5 m/s?

To find : What is the mass of a baseball.

Solution : We have given

Kinetic energy = 100 J.

Velocity = 5 m/s.

Kinetic energy = $(1)/(2)m v^(2)$ .

Where m = mass , v = velocity.

Plugging the values

100 = $(1)/(2)m (5)^(2)$ .

100 = $(1)/(2)m 25$ .

On multipkying both sides by 2

200 = 25 m

On dividing both sides by 25

mass = 8 kg.

Therefore, mass = 8 kg.

Casey said that 40 people were surveyed. Is his answer reasonable?

Answers

If 40 people were surveyed then it is reasonable

It depends on your population size, and if your sample is biased. If your sample was 40 out of 100, then yes, it would be reasonable. But if your sample was 40 out of 1000, then no because the sample is too small.
