Answer:
It’s mass would be the same
Explanation:
Mass and weight are often used interchangeably in everyday conversation. For example, our medical records often show our weight in kilograms but never in the correct units of newtons. In physics, however, there is an important distinction. Weight is the pull of Earth on an object. It depends on the distance from the center of Earth. Unlike weight, mass does not vary with location. The mass of an object is the same on Earth, in orbit, or on the surface of the Moon.
Net force acting on the car is 3 x 10^3 Newtons:
The answer is false..................
When a heavy football player and a light one run into each other, does the lighter player really exert as much force on the heavy player s the heavy player exerts on the light one. Yes. The interaction between the two players, the force each exerts on the other have equal strength.

The initial speed of the ball is 5 m/s
Explanation:
We can solve the problem by using the law of conservation of momentum: in absence of external forces, the total momentum of the skater + ball system must be conserved. So we can write:
where:
m = 5 kg is the mass of the ball
u is the initial velocity of the ball
M = 45 kg is the mass of the ice skater
V = 0.5 m/s is the final velocity of the skater+ball together
Solving for u, we can find the initial velocity of the ball:
