Anet force of 50 n is applied to a 10 kg cart that is already moving at 3 m/s. the final velocity of the cart was 8 m/s. for how long was the force applied
Answers: 1
Plan the equation on x direction (because the mass is moving on that way). The result would be: 
From that equation we know that the aceleration is 5m/s2.Also, we know (because it is a uniform line movement) that the aceleration is related with the speed. 
Clearing the equation: 
And replacing: 
So, the force is applied for 1 second.
