How about a1=V1-V01/t a2=V2-V02/t that leads to (V1-V01)*t/t*(V2-V02), we cancel out t and we get (V1-V01)/(V2-V02), now I need to know how you get velocity of cart and cart + 200grams.
Tried to get acceleration by converting grams to kilos, then dividing 0,3 meters with 0,2 kilos. Got 1,5, but I doubt its right. If 1,5 would be correct, I would just use ΣF⃗=ma⃗
Homework Statement
Influenced by certain force, cart moved from place and driven 0.5 meters distance. When 200grams weight was placed on cart it moved 0.3 meters during the same period of time. Calculate the mass of the cart.
