Solving a Physics Problem: Calculating Time on the Ground & in Air

In summary, A person is running and covers a distance of 100m. The time he was in contact with the ground and the time he remained in the air needs to be calculated. The person's speed and stride may play a role in the solution, and more information is needed to solve the problem.

dear friends
i have a problem in physics please solve it

it is that a man covers 100 m distance by running...so calculate the total time by that he was in contact with the groung and the time that the time he remain in the air...

numerically
d=100m
t(on the ground)=?
t(in the air)=?

please try to solve n post

thanx in advance

You don't think perhaps his speed and/or stride has something to do with this?

Tell you what, you go first, then we'll help you out from there. You can't solve it using just the information you gave us, though.
 

Related to Solving a Physics Problem: Calculating Time on the Ground & in Air

1. How do you calculate the time a projectile spends on the ground?

To calculate the time a projectile spends on the ground, you can use the equation t = √(2h/g) where t is the time, h is the height of the projectile, and g is the acceleration due to gravity.

2. How do you calculate the time a projectile spends in the air?

To calculate the time a projectile spends in the air, you can use the equation t = 2v₀sinθ/g where t is the time, v₀ is the initial velocity, θ is the angle of launch, and g is the acceleration due to gravity.

3. What is the difference between time on the ground and time in the air?

The time on the ground refers to the time that a projectile spends traveling horizontally after it has landed, while the time in the air refers to the time it spends in motion after being launched before it lands.

4. How does air resistance affect the time of a projectile?

Air resistance can affect the time of a projectile by slowing it down and changing its trajectory. This can result in a longer time in the air and a shorter time on the ground compared to a scenario with no air resistance.

5. Can you use the same equation to calculate time on the ground and time in the air?

No, the equations for calculating time on the ground and time in the air are different. Time on the ground is calculated using the initial height of the projectile, while time in the air is calculated using the initial velocity and angle of launch. However, both equations do include the acceleration due to gravity (g).
