.
Answer:
x = - 7
Step-by-step explanation:
Given
- 2(x + 5) = 4 ← distribute the parenthesis by - 2
- 2x - 10 = 4 ( add 10 to both sides )
- 2x = 14 ( divide both sides by - 2 )
x = - 7
Answer:
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
