250/20 =12 r10 when you divide 250 by 20 you will get 12 r10 because 20 cannot go into 2 but it can go into 25 so u place a 1 over the five because 1 goes into 25 once then subtract 25 from 20 and u will get 5. since 20 cant go into 5 bring the 0 down and it will become 50. 20 cant go into 50, 2 times so subtract 50 from 40 and u will get a remainder of 10 and since 20 cant go into 10 and there is nothing else to bring down the remainder is 10
A negative velocity means the object is going the opposite way of the positive direction. So a negative x component velocity is pointing the opposite way (left) of the positive direction (right). You can think of it as the cart is backing up as it faces the positive direction.
