Answer:
The final position is -69.8 m
Explanation:
Recall that displacement is defined as:
where represents the final position, and the initial position of the object (in our case 83.2 m). Since we also know the displacement (-153 m), we can solve the equation for the final position:
Answer:
1.59 m/s^2, 65.2°
Explanation:
F1 = 390 N North
F2 = 180 N east
m = 270 kg
Net force is the vector sum of both the forces.
F = 429.53 N
Direction of force
tan∅ = F1 / F2 = 390 / 180 = 2.1667
∅ = 65.2°
The direction of acceleration is same as the direction of net force.
The magnitude of acceleration is
a = F / m = 429.53 / 270 = 1.59 m/s^2
I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
Ex: You roll a ball. It slows down by friction.
II. Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).
Ex: You cannot kick a brick wall down, but you can kick a soccer ball because the brick wall is more massive.
III. For every action there is an equal and opposite re-action.
Ex:when a rocket lifts off, the rocket's action is to push down on the ground with the force of its engines, and the reaction is that the ground pushes the rocket upwards with an equal force.
Answer:
write: I think that we can only see one side of the moon because the moon rotates and spins on its axis at the same rate that the Moon orbits the Earth.
hope this is wht ur looking for. :)

Answer:
The force exerted on an electron is
Explanation:
Given that,
Charge = 3 μC
Radius a=1 m
Distance = 5 m
We need to calculate the electric field at any point on the axis of a charged ring
Using formula of electric field
Put the value into the formula
Using formula of electric field again
Put the value into the formula
We need to calculate the resultant electric field
Using formula of electric field
Put the value into the formula
We need to calculate the force exerted on an electron
Using formula of electric field
Put the value into the formula
Hence, The force exerted on an electron is
