Answer:
40.1m/s
Explanation:
This is a kinematics problem
x = 82m
a = -9.8m/s^2
v(initial) = 0
Find: v(final)
Using kinematics equation:
vf^2 = vi^2 + 2a(delta)x
vf^2 = 0 + 2*(-9.8)*(82)
vf = sqrt(1607.2) = 40.09m/s
The is traveling with a velocity of 40.1m/s when it hits the ground.
Answer:
make sure there spreaded out
Explanation:
<em>you have to spread them out because you dont want one half to be dry and the other side wet and if theres some that are white and some that are colored the color can bleed so yea spread hem out</em>
In a problem where a child is danger form drowning from a river who has a current of 3.1km/hr to east and the child is 0.6km fro the shore and the upstream is 2,5km from the dock. So base on the question the boat with a speed of 24.8 km/hr is 1.9 km because the child is 0.6 km off the dock so 2.5 minus 0.6
Answer:
True
Explanation:
Scientific laws are often written as expressions that contains variables and are laws that are binding themselves.
In science, laws are natural phenomenon that draws from careful observations that holds through following a series of detailed study. Within the range of assumed parameters, a law will always hold true.
Most laws in science are denoted using mathematical variables which helps to interpret them.
The variables shows the relationship between the different parts of the law.
For example, Newton's law of universal gravitation is expressed mathematically as shown below;
F = 
where G, m and r are all variables.
G is the universal gravitation constant
m is mass
r is the distance between them.
F is the gravitational force.
Most scientific laws are often expressed in this format.
