Answer:
The dog has more momentum than the pony.
Explanation:
To solve this problem, we must remember the formula for calculating momentum, which is given below:
momentum = p = m*v
where m represents the mass of the object and v represents the velocity of the object
Using this knowledge, let's calculate the momentum for the dog and the pony.
Dog: p = m*v = (2kg)*(41 m/s) = 82 kg*m/s
Pony: p = m*v = (75kg)*(1 m/s) = 75 kg*m/s
Since 82 > 75, we can conclude that the dog has more momentum.
Hope this helps!
 
        
             
        
        
        
we assume the acceleration is constant. we choose the initial and final points 1.40s apart, bracketing the slowing-down process. then we have a straightforward problem about a particle under constant acceleration. the initial velocity is v xi  =632mi/h=632mi/h( 1mi 1609m  )( 3600s 1h  )=282m/s (a) taking v xf  =v xi  +a x  t with v xf  =0 a x  = t v xf  −v xf   = 1.40s 0−282m/s  =−202m/s 2 this has a magnitude of approximately 20g (b) similarly x f  −x i  = 2 1  (v xi  +v xf  )t= 2 1  (282m/s+0)(1.40s)=198m
