The equivalent gravitational force is ~
We know that ~
where,
= mass of 1st object = 500 kg
= mass of 2nd object = 20kg
- G = gravitational constant =
- r = distance between the objects = 2.12 m
Let's calculate the force ~
Answer:
29.96m/s
Explanation:
Given parameters:
Initial speed = 25.5m/s
Acceleration = 1.94m/s²
Time = 2.3s
Unknown:
Final speed of the car = ?
Solution:
To solve this problem, we are going to apply the right motion equation:
v = u + at
v is the final speed
u is the initial speed
a is the acceleration
t is the time taken
Now insert the parameters and solve;
v = 25.5 + (1.94 x 2.3) = 29.96m/s
True.
It has been studied in a research study that claims birds have the ability and capability to regenerate their hair cells.
