Answer:
The frictional force needed to overcome the cart is 4.83N
Explanation:
The frictional force can be obtained using the following formula:
[tex]F= \mu R[/tex]
where [tex]\mu[/tex] is the coefficient of friction = 0.02
R = Normal reaction of the load = [tex]mgcos\theta[/tex] = [tex]25 \times 9.81 \times cos 10[/tex] = [tex]241.52N[/tex]
Now that we have the necessary parameters that we can place into the equation, we can now go ahead and make our substitutions, to get the value of F.
[tex]F=0.02 \times 241.52N[/tex]
F = 4.83 N
Hence, the frictional force needed to overcome the cart is 4.83N
