A car is moving with a velocity (3.0 m/s) x̂ + (1.0 m/s) ŷ and 3.0 seconds later its velocity is (6.0 m/s) x̂ - (3.0 m/s) ŷ. Wha
Mars2501 [29]

Here we know that the initial velocity of the car is given by:

V_i=(3.0\hat x+1.0\hat y)m/s

And the final velocity of the car is given by:

V_f=(6.0\hat x-3.0\hat y)m/s

It took 3 seconds to attain the final velocity, so we have t=3 s

Therefore, the acceleration can be obtained by:

V_f-V_i=a\times t

a=\frac{V_f-V_i}{t}

Plugging the values of the initial, final velocity and the time, we get:

a= \frac{(6\hat x-3\hat y)-(3 \hat x+1 \hat y)}{3} =\frac{6\hat x-3 \hat y -3 \hat x-1 \hat y}{3} =\frac{3 \hat x-4 \hat y}{3}

So the acceleration of the car is given by:

a=\frac{3 \hat x}{3} -\frac{4 \hat y}{3} =1 \hat x- \frac{4}{3} \hat y

Now we need to find the direction of the average acceleration of the car:

\theta=tan^{-1} \frac{y}{x}

Here, x and y are the coefficients of the 'x' and 'y' components of the vector:

\theta=tan^{-1}(\frac{-\frac{4}{3} }{1} )=tan^{-1}(\frac{-4}{3}) =-53.13^\circ

Therefore, the direction of the average acceleration of the car is -53.13^\circ.

josh is 6 years older than 4 times Kim's age. The sum of their ages is less than 31. what is the oldest Kim could be? show all y
Mice21 [21]

Answer:

4 years old.

Step-by-step explanation:

Lets say that Josh's age is j and Kim's age is k. As Josh is 6 years older than 4 times Kim's age, we can write this as an equation:

j = 4k + 6

This is, John's age is equal to four times Kim's plus 6 years.

We then know that, when summed their ages is less than 31, so:

k + j < 31

Replace John's age by our first equation:

k + 4k + 6 < 31

5k + 6 < 31

Subtract 6 in both sides:

5k + 6 - 6 < 31 - 6

5k < 25

Dividing both sides by 5:

5k/5 < 25/5

k < 5

So, Kim's age MUST be less than 5.

If we talk about discrete values, this is 1, 2, 3, 4, 5, 6...., we will say than the oldest Kim could be is 4. If Kim is 5 years old, the sum of ages is 31 and we need it ti be LESS than 31. (we are not considering fractional numbers as 4.5 years old).

So, Kim can be, at maximum, 4 years old.

Misha Larkins [42]

Answer:

c = -2

Step-by-step explanation:

-5c - 10 - 5c - 2 = 8

-10c - 12 = 8

      +12     +12

-10c = 20

/ -10    / -10

c = -2
