Aforce of 19 newtons is applied on a cart of 2 kilograms, and it experiences a frictional force of 1.7 newtons. what is the acceleration of the cart? a. 8.6 meters/second2 b. 9.0 meters/second2 c. 9.5 meters/second2 d. 10.5 meters/second2 e. 0.8 meters/second2

option A

a = 8.65 m/s²

Step-by-step explanation:

Given that,

force applied on a cart (forward direction) = 19N

frictional force experience by cart (backward direction) = 1.7N

mass of the cart = 2 kg

Frictional force always opposes applied force, so the Resultant force on the cart would have to be 19N - 1.7N.

Formula to use

Resultant force = ma

plug values in the formula

19 - 1.7 = 2(a)

17.3 = 2(a)

a = 8.65 m/s²

so the acceleration of the cart is 8.65m/s²

i have not got your picture clearly so see it once again
