Answer:
a The larger football player will move, but because of his larger mass, his velocity will be much slower than the smaller player
Explanation:
When the collision takes two equal and opposite forces are created at the point of collision . The force created on the bigger mass will force it to accelerate and the force on moving smaller mass will force it to slow down .
Because of bigger mass , acceleration on bigger mass will be less and hence its velocity will be less .
Hence option a is the right answer.
Answer:
Explanation:
Provided the car did not collide with anything during its slide,
Kinetic energy will convert to work of friction
½mv² = Fd
½mv² = μmgd
v = √(2μgd)
v = √(2(0.300)(9.81)(28.0))
v = 12.8377...
v = 12.8 m/s
Answer:
1b. It is called law of the inertia because it overcomes intertia
1c. Why I feel pressed is because of the acceleration trying to overcome inertia .
2a.The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.
2b. If the force were doubled, you double The mass it's acting on.
2c. A car with large mass will use more fuel because it needs more energy to overcome the inertia force.
Explanation:
Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless being acted upon by an external force.
