Answer:
 d) An object that is speeding up always has a positive acceleration, regardless of the direction it travels.
Explanation:
a ) a) An object that is slowing down while traveling in the negative x-direction always has a positive acceleration.
It has negative acceleration in  the negative x-direction. 
b) An object that is speeding up while traveling in the negative x-direction always has a positive acceleration. 
It has a positive acceleration in the negative x-direction'
 c) An object that is slowing down always has a negative acceleration, regardless of the direction it travels. 
It has a positive  acceleration in opposite direction. 
e ) An object that is slowing down always has a positive acceleration, regardless of the direction it travels.
It has a positive acceleration only in opposite direction . 
 
        
             
        
        
        
Answer:
The value is  
Explanation:
From the question we are told that 
   The radius of the tires is  
    The  angular acceleration is  
Generally the linear acceleration is mathematically represented as 
      
=>

Answer:
It depends on the potential energy it has ontop of the ramp. The marble has the same potential energy was the kinetic energy without changing the ramp incline or moving it. What kinetic energy shows is what potential energy made it to be, so we look at how the ramp is placed. If the ramp is a steep incline the kinetic energy will be fast. It depends on the weight of the marble too. If the marble is heavy the potential energy will slowly tansition to kinetic energy while a  light marble will transition to kinetic energy fast. But marbles are light so there we have it. It basically goes from potential energy to kinetic energy to thermal energy to potential energy.  Make me brainliest pls :)
