Answer:
Runner A will be 0.05 km from the flagpole, and runner B will be 0.07 km from the flagpole
Explanation:
We can find when their paths will cross as follows:
Where:
is the final position
is the initial position
v₀ is the initial speed
t is the time
a is the acceleration = 0 (since they are running with a constant velocity)
When their paths cross we have:
Now we can find the final distance of each runner.
Therefore, runner A will be 0.05 km from the flagpole, and runner B will be 0.07 km from the flagpole.
I hope it helps you!
Answer:
Explanation:
<u>Mass and Weight</u>
The mass of an object is a measure of the object's amount of matter it contains. It's expressed in Kilograms or similar units.
The weight of an object is a measure of the force exerted on the object by gravity. It's often expressed in Newtons or similar units.
The formula to calculate the weight of an object with known mass m is:
W = m.g
Where g is the acceleration of gravity in the place it's located. We are given the mass of an electron:
On Earth, the acceleration of gravity is:
Thus, the weight is:
Answer:
7.5 km/hr
Explanation:
All you have to do is divide 15 km by 2 hours and you get 7.5 km/hr.
Answer:
176.4 m
Explanation:
U = 0, t = 6s, g = 9.8 m/s^2
Use second equation of motion
H = ut + 1/2 gt^2
H = 0 + 0.5 × 9.8 × 6 × 6
H = 176.4 m
It is the displacement from the point of dropping of object.
