Velocity is speed and the direction of the speed. Acceleration is the rate at which Velocity is changing, and the direction in which it's changing.
Answer:
120,000
Explanation:
Millimeters to meters calculation-
Multiply by 1,000.
120 x 1,000 = 120,000.
This is the correct answer and formula.
Hope this helps!
Answer:
Increases

Increases
Explanation:
I don't know if you answered your own question but I'll just answer this for others confused ahh
Explanation:
It is given that,
Total mass is 70 kg
The truck exerts a constant force of 20 N.
Then the net force is given by :
F = ma
a is acceleration of rider

Initial velocity of rider is 0. So, using equation of kinematics to find the final velocity as :

Since, 1 m/s = 2.23 mph
4.28 m/s = 9.57 mph
So, the speed of the rider is 4.28 m/s or 9.57 mph.
Answer: Use the formula q = m·ΔHv in which q = heat energy, m = mass, and ΔHv = heat of vaporization.
