Answer:
-5m/s²
Explanation:
Given parameters:
Initial velocity = 25m/s
Time = 5s
Final velocity = 0m/s
Unknown:
Acceleration of the car = ?
Solution
The acceleration of a body is the rate of change of the velocity of the body with time.
Acceleration =
So;
Acceleration = = -5m/s²
The car is decelerating at a rate of 5m/s²
Answer:
Planning and performing an experiment to answer the question.
Explanation:
Answer:
varn=n1+1ehvkT–1
Explanation:
This is Einstein's equation.
Answer:4.04 m
Explanation:
mass of athlete
initial speed
To get the maximum height h of Athlete we conserve energy i.e.
Kinetic Energy of Athlete=Potential energy gained by athlete
(b)Speed at half of maximum height
Considering v be the velocity at half of maximum height
conserving Energy we can write
(as )
thus
So Athlete interact with the gravitational Field of Earth
