The distance a spring stretches varies directly as the amount of weight that is hanging on it. A weight of 2.5 pounds stretches

a spring 18 inches. Find the stretch of the spring when a weight of 6.4 pounds is hanging on it.

We use the equation y = kx
y = 18, x = 2.5

18 = k2.5
k = 7.2

x = 6.4
y = 7.2*6.4
y = 46.08

hope this help

Answer:

The stretch of the spring is 46.08 inches.

Explanation:

Given that,

Weight = 2.5 pounds

Stretches a spring = 18 inches

new weight = 6.4

We need to calculate the stretch of the spring

let stretch of the spring is x .

Using formula of restoring force

F=-kx

For first weight,

2.5=k\times18....(I)

For another weight,

6.4=k\times x....(II)

Ratio of equation (I) and (II)

\dfrac{2.5}{6.4}=\dfrac{18}{x}

x=\dfrac{18\times6.4}{2.5}

x = 46.08\ inches

Hence, The stretch of the spring is 46.08 inches.

If a girl is running along a straight road with a uniform velocity 1.5m/s find her acceleration ​
Jlenok [28]

Answer:

Dear user,

Answer to your query is provided below

Acceleration is zero because of no change in velocity.

Explanation:

Remember that velocity is a vector quantity and a vector can change in 3 ways

•Magnitude only

•Direction only

•Both magnitude and direction.

Now the magnitude of velocity (speed) can stay constant while the direction is changing. This is the case in circular motion.

In the question above, it is mentioned that the girl is moving along a straight road. Therefore no change in direction of velocity.

stiks02 [169]

Answer:

The correct option is D

Explanation:

This question can be better understood when discussed using the Newton's first law of motion which states that an object would continue to move with a uniform speed (in a straight line) unless acted upon by an external force. What happens here (in the question) is that the bike rider would have continued moving at a constant speed (to the right) if not for the opposing force of the wind that acted against her (to the left). <u>This wind/force would cause her speed to reduce or slow down (as posited by the law)</u>.
