Answer: In your right wrist
Explanation:
Given:
m = 4 kg, the mass of the object
h = 5 m, distance fallen
Neglect air resistance.
The PE (potential energy) is
PE = mgh = (4 kg)*(9.8 m/s²)*(5 m) = 196 J
The PE is converted into KE (kinetic energy) after the fall.
Therefore the PE decreased by 196 J ≈ 200 J
Answer: d. It has decreased by 200 J
Answer:
d. Direction and magnitude
Explanation:
The two components of a vector are its magnitude and direction.
Magnitude is the quantity of the substance
Direction is the path.
- Other quantities are called scalar quantities.
- Scalar quantities have only magnitude but no direction.
Examples of vector quantities are velocity, displacement, acceleration.
Answer:
v = 1.00 m/s east
Explanation:
Conservation of momentum
Let east be the positive direction
2.00(4.00) + 6.00(0.00) = 2.00(v) + 6.00(1.00)
v = 1.00 m/s east
The two items have stuck together.
