Answer:
7.41 m/s
Step-by-step explanation:
Force of a car inclined at an angle
F=mg Sin Θ where; m = 2956 kg , g = 9.8m/s² , Θ = 35⁰
F = 2956 x 9.8 x Sin 35 = 16615.82 N
Net force due to friction = 16615.82 - 3080 = 13535.82 N
To calculate acceleration; F= Ma
13535.82 = 2956 x a
a = 4.58 m/s²
From equation of motion
V² = 0 + (2 x 4.58 x 6)
V =
V = 7.41 m/s

Answer:
middle term = 7x
Step-by-step explanation:
in order to find the middle term, we will expand the bracket on the left hand side and compare the expressions on both sides.
(x + 2) (3x + 1) = 3x² + ___ + 2
let the unknown expression = y
(x + 2) (3x + 1) = 3x² + y + 2
Expanding the bracket on the left hand side by multiplication:
x + 2( 3x + 1) = (x × 3x) + (x × 1) + (2 × 3x) + ( 2 × 1)
= 3x² + x + 6x + 2
= 3x² + 7x + 2
Comparing with the expression on the right hand side:
3x² + 7x + 2 = 3x² + y + 2
∴ y = 7x
middle term = 7x
