Explanation:
From the question we are told that
The distance travel in 4.22 s is
The mass of the cart plus the fan is
Generally from kinematic equation we have that
Here u is the initial velocity with value
So
=>
Generally the net force is
=>
=>
Gnerally the new mass of the cart plus the fan is
The distance considered is
Generally the new acceleration of the cart is mathematically represented as
=>
=>
=>
Gnerally from kinematic equation we have
Here u is the initial velocity and the value is zero because it started from rest
=>
=>
