Answer:

2.26m/s^2

Step-by-step explanation:

65km/hr = 18.05m/s

$a = \frac{v - u}{t}$

v = 18.05m/s

u = 0 m/s

t = 8s

$a = \frac{18.05 - 0}{8}$

$a = \frac{18.05}{8}$

a = 2.26m/s^2

Aliun [14]

Answer:

$A=9.5\ ft^2$

Step-by-step explanation:

we know that

The area of the shaded region is equal to the area of triangle plus the area of semicircle

$A=\frac{1}{2}bh+\frac{1}{2}\pi r^{2}$

we have

$b=4\ ft$

Find the height of the right triangle applying the Pythagorean Theorem

$5^2=h^2+4^2$

$h^2=9\\h=3\ ft$

The radius of the semicircle is half the height of triangle

$r=3/2=1.5\ ft$

substitute in the formula

$A=\frac{1}{2}(4)(3)+\frac{1}{2}(3.14)(1.5)^{2}$

$A=6+3.5=9.5\ ft^2$
