8. 36.8 = [11.5 – (2.5 X 3)]2
Anestetic [448]

Answer:

[11.5-(2.5*3)]^2=16

Step-by-step explanation:

We want to evaluate [11.5-(2.5*3)]^2

Let us evaluate within the parenthesis first:

[11.5-(2.5*3)]^2=[11.5-(7.5)]^2

\implies [11.5-(2.5*3)]^2=[11.5-7.5]^2

We again subtract within the bracket to obtain:

[11.5-(2.5*3)]^2=[4]^2

This finally gives us:

[11.5-(2.5*3)]^2=16

1- The acceleration of a particle is defined by the relation a = 6 ft/s 2. Knowing
TiliK225 [7]

Answer:

The initial velocity of the particle is

v' = -6 - 6.2 = -18 ft/s

at t = 5s, the velocity is v = -18 + 6.5 = 12 ft/s

the position is

x =  - 32  - 18 \times 5 +  \frac{1}{2}  \times 6 \times 5 {}^{2}  =  - 47 \: ft

the total distance traveled is

s =  | \frac{12 {}^{2}  - 18 {}^{2} }{2 \times 6} |  = 15 \: ft
