I need help with this word problem please

Anika [276]

Answer:

-60 m/s²

Step-by-step explanation:

We are not given the velocity of the plane at landing but we are given velocities at two time periods

V₅, the velocity of the plane 5 seconds after landing is 110 m/s

Plugging this into the velocity equation we get

$\bold{v_5 = a.5 + v_0 = 5a + v_0}$ (1)

Similarly

$\bold{v_{15} = a.15 + v_0 = 15a + v_0}$ (2)

Subtract (1) from $v_{15} - v_5 = (15a + v_0) - (5a + v_0) = (15a-5a) + (v_0-v_0) = 10a$

Therefore $a = \frac{v_{15} - v_5}{10}$

Given $v_{15}= 50 m/s \textrm{ and } v_5 = 110m/s$

this evaluates to

$a = (50-110)/10 =$ -60 m/s²

The negative value is because the plane is actually decelerating which is a negative number

PLEASE HELP<br> Complete the table by computing the amount in the account at the end of each period.

skad [1K]

Answer:

See below

Step-by-step explanation:

Initial Principal P₀ = 1000
End of first period = 1000 + 1000*0.02/4 = 1005
End of second period = 1005 + 1000*0.02/4 = 1010
End of third period = 1010 + 1000*0.02/4 = 1015
End of fourth period = 1015 + 1000*0.02/4 = 1020
