Projectile Problem: Stones Meet at Height

In summary, two stones are thrown straight up with the same initial velocity of 10.5 m/s, with the second stone being thrown 1.0 s after the first. The two stones will meet at a certain height above the point of release. To solve this problem, one must use the kinematics equations and take into account that the time for the second stone is (t-1). By using the equation t=-4.9t^2+v0t+h, one can solve for the height at which the two stones will meet.

Suppose you throw a stone straight up with an initial velocity of 10.5 m/s and, 1.0 s later you throw a second stone straight up with the same initial velocity. The first stone going down will meet the second stone going up. At what height above the point of release do the two stones meet?

What have you tried? Where are you stuck?

You need to know the kinematics equations to answer this problem.

HINT: The time for the second stone is (t-1)

hm...basically i need help for the whole question
i have no idea how to even start the question

s(t)=-4.9t2+v0t+h

Using this and the previous suggestion, you shouldn't have any trouble.
 

1. What is a projectile problem?

A projectile problem is a type of physics problem that involves calculating the motion of an object that is thrown or launched into the air, typically in a parabolic path.

2. What is the "Stones Meet at Height" projectile problem?

The "Stones Meet at Height" projectile problem involves two objects being launched at different angles and speeds, with the goal of finding the height at which the two objects will meet.

3. How do you solve the "Stones Meet at Height" projectile problem?
