Answer:
The second student with mass 70kg has more momentum
Explanation:
Using the formula:
p = m × v
Where;
p = momentum (kgm/s)
m = mass (kg)
v = velocity (m/s)
According to this question, two students are running in a cross country race.
Student 1 has the following; m = 60kg, v = 7m/s
Student 2 has the following; m = 70kg, v = 7m/s
Using p = mv
Student 1, p = 60 × 7 = 420 kgm/s
Student 2, p = 70 × 7 = 490 kgm/s
From the result of the above calculations, student 2 with mass 70kg has more momentum.
Answer: 50.806 cm is the correct answer.
Explanation: First divide 6104.5 cm^2 by 22.3 cm.
*Note: When dividing units, subtract the exponents, and when multiplying units simply add the exponents.
Then continue by subtracting 324.55 cm - 273.74 cm.
This should give you an answer of 50.806 cm.
1Hz = 1 cycle per second
19 cycles / .5 seconds = 38Hz
