Answer:
0.278 m/s
Explanation:
We can answer the problem by using the law of conservation of momentum. In fact, the total momentum before the collision must be equal to the total momentum after the collision.
So we can write:
where
m = 0.200 kg is the mass of the koala bear
u = 0.750 m/s is the initial velocity of the koala bear
M = 0.350 kg is the mass of the other clay model
v is their final combined velocity
Solving the equation for v, we get
Answer: False, the factors that can affect the weight are the mass of the planet and the radius of the planet.
Explanation:
First, we can write the weight as:
W = m*g
where m is the mass and g is the gravitational acceleration.
For example. g in the Earth is 9.8m/s^2, and g on Mars is 3.71 m/s^2, so you will weight more in Earth than on Mars, and Earth is closer to the Sun than Mars, so the statement is false.
Now, the gravitational acceleration depends primarily on the mass of the planet, this is because the gravitational force between two objects can be written as:
F = G*M*m/r^2
Where M is the mass of the planet, and m is your mass and r is the distance between you and the planet, if you are in the surface, r is the radius of the planet.
Here we can see that planets with more mass and smaller radius (more density) have the strongest gravitational force on any object near them.
