Answer :
The cart of the supermarket will move 3.99 m if the shopper places an 84 N child in cart and is pushing.
Given that,
Mass of the cart = 25.1 kg
Horizontal force = 13.3 N
It is pushed for 3.6 sec
Mass of the cart and child = Total force/ Acceleration = (25.1* 9.8 + 84)/9.8 = 33.67 kg
From the equations of motion, we know,
Initial velocity = 0
Time t = 4.5 s
Distance s = ut + 1/2* a* t² = 0 + 1/2* (13.3/33.67)* (4.5)² = 3.99 m
Thus, the cart will move for 3.99 m after placing the child.
The question is incomplete. The complete question is 'A shopper in a supermarket pushes a loaded cart with a horizontal force of 13.3 Newtons. The cart has a mass of 25.1 kg and is pushed for 3.60 seconds, starting from rest.'
