Use the equation, F= m(mass)x a (acceleration) to find the net force.
vovikov84 [41]3 years ago
3 0

Answer:

a. 2000 N

b. acceleration of the motorcycle would decrease

Explanation:

a. acceleration = (final speed - initial speed)/time

a = (30 - 0)/3 = 10 m/(s^2)

Force = mass * acceleration

F = 200 * 10 = 2000 N

b. If the the coefficient of friction between the tire and the pavement increased greatly, part of the force generated by the engine would go to overcome this friction, then the force that goes into acceleration of the motorcycle would be less than case a, as a consequence, its acceleration would decrease (mass remains the same).

How do Newton's laws of motion explain why it is important to keep the ice smooth on a hockey rink so that players can
lord [1]

Answer:

I'm not sure..but please refer to your teacher later.

Answer: Based on Newton's First law of motion (where inertia is involved), smooth ice increases the forceused to accelerate the hockey puck.

Explanation;

  • smooth ice reduces the resistances between the surface of the figure skates and the ice itself.
  • based on inertia theory ; the heavier the weight, the larger the inertia.. which explains it takes alot of force to move a heavier object than the lighter ones.. it also hard to *stop* the motion of heavier objects than the lighter ones.
  • now let's look at the design of the player shoe itself, they have a sharp blade at the bottom of the figure stakes.. which takes us to the law of the force.. the smaller the surface area, the more forces acting on it. So, players force (weight, F= mg) acts on the tip of the blade and on the ice
  • high inertia (run fast) and high force (attack opponent and pass puck) enables them to perform well in playing hockey
  • Thus if there's no resistance and the inertia of the player is high then they could run and pass the puck quickly

Answer:

mechanical waves,

.

the quality of a sound governed by the rate of vibrations producing it; the degree of highness or lowness of a tone.

.

If the amplitude increases the volume increases and vice versa.

.

The type of medium affects a sound wave as sound travels with the help of the vibration in particles.

.

The higher the frequency, the shorter the wavelength.
