An athlete gains 300J of KE when running at 3m/s. Find the mass of the athlete.

Physics
1 answer:
Debora [2.8K]2 years ago
3 0
KE and PE are the same so it would end up being 300=3x9.8xm and work backwards to find 300=29.4m divide and get 10.2 significant figures will make it 10

A line of dominos is knocked down. Which explanation is true?
Llana [10]

B: an increase in acceleration caused an increase in force.

This is based on the concept of force on an object.

Now, formula for force is commonly known as;

Force = mass × acceleration

Now, mass and acceleration are the input values that make the output which is the Force to either increase or decrease.

  • Now, for the line of dominoes to fall, it means that the force was so overwhelming that the dominoes couldn't resist it.

Now, this output which is the force became so much as a result of the increase in acceleration of the motion that triggered its movement.

Moreover, the force is directly proportional to the acceleration!

Thus, we can say that an increase in acceleration caused an increase in force.
