Answer:
33 kg m/s
Explanation:
The momentum of an object is given by:
where
m is the mass of the object
v is the velocity of the object
In this problem, the total mass of the child and the wagon is m =22 kg, while the velocity is v = 1.5 m/s, therefore the momentum is
Answer: When the flashlight is turned on, the chemical energy stored in batteries is converted into electrical energy that flows through wires of flashlight. This electrical energy is then transformed into light and heat energies.
Explanation:
ANSWER
EXPLANATION
A sketch of the vector is shown in the diagram in the attachment.
The side adjacent to the angle we want to find is 3.5 units and the opposite side is 3 units.
Let the angle between the vector and the x-axis be
then,
This implies that,
The correct answer is B
Therefore the angle 40.6° to the nearest tenth.
