Answer:

1.a basketball that was thrown in the air falls to the ground

Explanation:

1.a basketball that was thrown in the air falls to the ground

From newton law of universal gravitation, it state that a object of any mass will  have the tendency to come down when throw to the atmosphere.

this is the reason why acceleration due to gravity of any object thrown up are always the same. Acceleration due to gravity on earth is 9.8 m/s2.

How much force is needed to accelerate a 68 kilogram-skier at a rate of 1.2 m/sec^2?
luda_lava [24]
The sum of forces = mass x acceleration

Ignoring all resisting forces like friction and air resistance, the only force is gonna be the one pushing the skier

So, 
Force = mass x acceleration

Now, we substitute the values given

Force = 68 x 1.2

And therefore, Force = 81.6 N

Your car is stalled in the middle of a large patch of ice (assumed to be frictionless). You have a friend that has thrown a rope
Gnoma [55]

Answer:

The time depends on the distance that they have to travel

x(t) = \frac{0.3846t^{2} }{2}

Explanation:

The only horizontal force exerts over the car and you, it is the force that your friend is applied

Newton's Second Law of Motion defines the relationship between acceleration, force, and mass, thus

\sum{F} = ma

        550 = 1430a

            a = 0.3846 m/s2

             

The car and you have a motion under constant acceleration, then theirs position to a time-based is:

x(t) = x_{0} + v_{0}t +\frac{at^{2} }{2}

By the initial conditions

x(t) = \frac{at^{2} }{2}

x(t) = \frac{0.3846t^{2} }{2}

The time depends on the distance that they have to travel
