To solve chase equations, you first
determine the time that is required for the two objects to come together
– then, you use that time to determine the position of their collision. To work this type of problem, one object is considered the leader and the other is the pursuer.
How do you solve catch up problems in physics?

- Plan a Solution. Turn the concepts into math. A. …
- Execute the Plan. This is the easiest step – it’s just the algebra/calculus/etc. A. …
- Evaluate the Answer. Be skeptical.
How do you solve kinematic problems in physics?
- Write down every quantity the problem gives you (initial and final position, initial and final velocity, acceleration, time, etc)
- Write down which quantity you are trying to find.
- Find the kinematic equation (or sometimes two equations) to relate these quantities.
- Solve the algebra.
How do you analyze a physics problem?
- Don’t Panic.
- Try to Understand the Situation.
- Read the Question Carefully.
- Organize the Information.
- Sketch the Scene.
- Verify Units.
- Consider your Formulas.
- Solve.
How do you determine when two objects will pass each other?
If
mindist > radius_A + radius_B
, then the two circles will never touch. If is less than or equal, then they will touch and you know there will be a collision within mintime -seconds.
What are the 5 kinematic equations?
Building on what you have learned so far and what Galileo presented, we have what my physics teacher, Glenn Glazier, liked to call the Five Sacred Equations of Kinematics for constant acceleration. In these equations,
v is velocity, x is position, t is time, and a is acceleration.
Remember, Δ means change in.
What is work formula?
To express this concept mathematically, the work W is equal to the force f times the distance d, or
W = fd
. If the force is being exerted at an angle θ to the displacement, the work done is W = fd cos θ.
What are the three steps for solving most physics problems?

Which formula will help you solve how fast the object is moving?
To find out something’s speed (or velocity) after a certain amount of time, you just multiply the acceleration of gravity by the amount of time since it was let go of. So you get: velocity = -9.81 m/s^2 * time, or
V = gt
. The negative sign just means that the object is moving downwards.
How do you find time with two velocities and distance?
Rate of change in position, or speed, is
equal to distance traveled divided by time
. To solve for time, divide the distance traveled by the rate. For example, if Cole drives his car 45 km per hour and travels a total of 225 km, then he traveled for 225/45 = 5 hours.
How do you figure out when two trains will meet?
The meeting point for the trains is given by
−52.5
x+409.5=48x, or 409.5=100.5x. This yields x=27367, or 4 hours and 4 minutes, and therefore the trains meet at 2.04 a.m.
What are the 3 kinematic equations?
Our goal in this section then, is to derive new equations that can be used to describe the motion of an object in terms of its three kinematic variables:
velocity (v), position (s), and time (t)
. There are three ways to pair them up: velocity-time, position-time, and velocity-position.
What is a formula of time?
time
= distance ÷ speed
.

- t Time interval tqquadtext{Time interval}~ tTime interval.
- v Final velocity vquad ~~~text{Final velocity}~ v Final velocity.
