The net force on the shopping cart is 12 N to the right.
This is a question related to Newton's Laws. It can be solved by using a Free body diagram, which shows all the forces acting on the object. There are 4 forces acting on the object:
Forces (1) and (2) cancel each other because they have the same magnitude, and the overall force is given by the addition of forces (3) and (4)
The positive value indicates that the shopping cart is moving to the right.
Have a nice day!
The answer is positive.
In a middle of an atom, nucleus, contain neutrons (neutral charge) and protons (positive charge) so it will become positively charge nucleus.
v = 6.05 m/s
The mass of the brick, M = 21 kg
The velocity of the brick, U = 6.1 m/s
The mass of the cart, m = 2.9 kg
The velocity of the cart, u = 0.26 m/s
The combined mass of the brick and the cart, v = ?
According to the law of conservation of linear momentum,
Combined final momentum = sum of the initial momentum
(M + m)v = MU + mu
v = MU + mu / M + m
= 21 x 6.1 + 2.1 x 0.26 / (21 + 0.26)
= 6.05 m/s
Hence, the combined velocity of the cart and the brick is, v = 6.05 m/s
