A ball rolling on grass has more friction than a ball rolling on tile

Answer:

When you slide an object there is less friction than when you roll it. an object's acceleration (change in speed) depends on the mass of the object and the amount of force applied on it. an object at rest stays at rest unless a force acts on it. ...

valentinak56 [21]

Answer:

15193.62 m/s

Explanation:

t = Time taken = 6.5 hours

u = Initial velocity = 0 (Assumed)

m = Mass of rocket = 1380 kg

F = Thrust force = 896 N

v = Final velocity

a = Acceleration of the rocket

Force

F=ma\\\Rightarrow a=\frac{F}{m}\\\Rightarrow a=\frac{896}{1380}\\\Rightarrow a=0.6493\ m/s^2

Equation of motion

v=u+at\\\Rightarrow v=0+0.6493\times 6.5\times 60\times 60\\\Rightarrow v=15193.62\ m/s

The velocity of the rocket after 6.5 hours of thrust is 15193.62 m/s

One of the fastest recorded pitches major-league baseball, thrown by nolan ryan in 1974, was clocked at 100.8 mi/hr. If a pitch
lawyer [7]

<u>Answer:</u>

 The ball fall vertically 2.69 ft by the time it reached home plate 60.0 ft away.

<u>Explanation:</u>

    Fastest recorded pitches major-league baseball, thrown by nolan ryan in 1974 = 100.8 mi/hr = 44.8 m/s

    The horizontal distance to home plate = 60.0 ft = 18.288 m

  We have the horizontal velocity = 44.8 m/s

    So time taken = 18.288/44.8 = 0.408 seconds.

  The distance traveled by baseball vertically is found out by equation s=ut+\frac{1}{2} at^2

  Here u =0m/s, a = 9.81 m/s^2 and t = 0.408 s

 Substituting

     S = 0*0.408+\frac{1}{2} *9.81*0.408^2 = 0.82 m\\ \\S = 0.82 m= 2.69 ft

So vertical distance traveled = 0.82 m = 2.69 ft

Mariana [72]
Answer: C

Explanation:
The acceleration does not depend directly on the mass of the object.

Newton's Law is Force = Mass x Acceleration.
Therefore, Acceleration  = Force/Mass

The same force is applied in both cases.
Therefore acceleration is inversely proportional to mass.
As mass decreases, acceleration increases.
