A child riding a bicycle at 5 meters per seconds accelerates at 2.0 meters per second for 4.0 seconds. What is the child's speed

slega [8]

Explanation:

Using Kinematics,

We have v = u + at.

=> v = (5m/s) + (2.0m/s²)(4.0s)

=> v = 13m/s.

Hence the child's speed is now 13m/s.

Find the value of 15.0 N in pounds. Use the conversions 1slug=14.59kg and 1ft=0.3048m. Express your answer in pounds to three si

kotykmax [81]

Given the equivalent value to convert the units from kilograms to slug and feet to meters, we will proceed to define the equivalence of the 'Newton' in simplified units, that is,

$1N=1kg\cdot m\cdot s^{-2}$

Then,

$15.0N=15.0kg\cdot m\cdot s^{-2}$

Converting this value to British units we have that

$15N = 15.0kg\cdot m\cdot s^{-2} (\frac{1slug}{14.59kg})(\frac{1ft}{0.3048m})$

$15N = 3.37 slug \cdot ft \cdot s^{-2} (\frac{1 lb \cdot ft^{-1}}{1slug})$

$15N =3.37lb$

Therefore the value of 15.0 N in pounds is 3.37 lb.

How do biotic and abiotic conditions change during secondary succession??

klasskru [66]
