Answer 1

Explanation:

the sand will moving with cart

Answer 2

Answer:

moving with cart

Explanation:

Let mass of cart be m1 and mass of sand be m2, and velocity of sand be v2. Now by Law of Conservation of Momentum, (m1+ m2)×v= m1×v+ m2×v2 Cancelling m1×v from both sides: m2×v2=m2×v Or, v2=v. Thus, the sand is moving in the same direction as the cart and with the same speed= it is moving with cart.

hope it helps.........
