<u>Displacement at t = 0</u> :

  • x = 4 cos(π (0) + π/4)
  • x = 4 cos(π/4)
  • x = 4 × 1/√2
  • <u>x = 2√2 meters</u>

<u>Displacement at t = 1</u> :

  • x = 4 cos (π (1) + π/4)
  • x = 4 cos (π + π/4)
  • x = -4 cos(π/4) [∴ cos is negative in the interval (π, 3π/2)
  • x = -4 × 1/√2
  • <u>x = -2√2 meters</u>

<u>Displacement between t = 0 and t = 1</u> :

  • -2√2 - 2√2
  • \boxed {-4\sqrt{2}}

∴ The displacement between t = 0 and t = 1 is -4√2 meters.

Answer:

-4\sqrt{2}  m

Step-by-step explanation:

Similar question to the previous one you asked, and I swear I will not make the same mistake again :)

First we will find the displacement at t = 0 and t = 1 to find both displacements.

t = 0,

x(0)=4cos(\pi (0)+\frac{\pi }{4} )=4cos(\frac{\pi }{4} )\\=4(\frac{\sqrt{2} }{2} )\\=2\sqrt{2} m

t = 1,

x(1)=4cos(\pi (1)+\frac{\pi }{4} )=4cos(\pi +\frac{\pi }{4} )\\=4(-\frac{1}{\sqrt{2} } )\\=-\frac{4}{\sqrt{2} }

Total Displacement = Final Position - Initial Position

= x(1) - x(0)

= -\frac{4}{\sqrt{2} } -2\sqrt{2} \\=-4\sqrt{2}  m

Komok [63]

Answer:

1824 in.

Step-by-step explanation:

First find the area of the two shapes you split that are the rectangle and triangle:

Rectangle Area:

48 * 32 = 1536

Area- 1536 in.

Triangle Area:

48 * 12 * 1/2

       or

48 * 12 divided by 2

= 288 in.

Now add the two areas up:

1536 + 288 = 1824 in.
