Momentum = (mass) x (speed)
Momentum = (8 kg) x (5 m/s)
Momentum = 40 kg-m/s
Answer:
B
Explanation:
Friction acts in a direction opposite to the motion of an object
Explanation:
Not enough information. It really depends on the technical details of the car ( the data provided is offering just the human factor of the reaction, not the time for getting the impulse through when using the breaks
The answer is 0.981 J
E = m · g · h<span>
E - energy
m - mass
g - gravitational acceleration
h - height
We know:
E = ?
m = 0.10 kg
g = 9.81 m/s</span>²
h = 1 m
E = 0.10 kg * 9.81 m/s² * 1 m = 0.981 J
