Momentum = 0.5 * 4 = 2
to conclude the man’s velocity after he throws the piece of equipment, divide
this number by the man’s mass.
v = 2/90
This is about 0.0222 m/s. To know if he can move 6 meters at velocity in
4minutes, use the following equation.
d = v * t, t = 4 * 60 = 240 s
d = 2/90 * 240 = 5⅓ meters.
This is ⅔ of a meter from the spaceship. To know the velocity that he must have
to move 6 meter, use the same equation.
6 = v * 240
v = 6/240
This is about 0.00416 m/s.
His final momentum = 90 * 6/240 = 2.25
To know the velocity of the package, divide this number by the mass of the
package.
v = 2.25/0.5 = 4.5 m/s
Because real electrons are in an electron cloud, not layers
Answer:
-2.67 m/s²
Explanation:
a = Δv / Δt
a = (14 m/s − 30 m/s) / (6 s − 0 s)
a = -2.67 m/s²
Answer:
False.
Explanation:
provided the distance between the forces remains the same, the force will <em>increase</em> with increased charge, whether attractive or repulsive.
Momentum is a property of a moving object that makes it hard to stop. It equals the object's mass times its velocity.
