Homework Statement
A bike accelerates at 1m/s^2 from rest. (0 meters per second) After 10 seconds a car accelerates at 2m/s^2 from rest.
Homework Equations
When are they going to meet, and where?
cepheid said:what fact is true about those positions when the vehicles "meet?"
igurmendez said:Oh, i didn't know about that sorry.
Well they indeed start from the same location.
I have been trying to solve this problem for the last 25 minutes but I can't find a soultion. I have been trying with these formulas:
Final Velocity = (Acceleration)(Time)
Distance = (Final Velocity/2) Time
Distance =(Acceleration x Time^2)/2
Final Velocity^2 = 2(Acceleration)(Distance)
igurmendez said:(The formulas include Starting Velocity, but as it is ZERO, I just ignored them;
igurmendez said:That's maybe what I'm missing, what is that fact?
Acceleration is defined as the rate of change of velocity over time. It is a measure of how quickly an object's speed or direction is changing.
Acceleration can be calculated by dividing the change in velocity by the change in time. This can be written as a = (vf - vi) / t, where a is acceleration, vf is final velocity, vi is initial velocity, and t is time.
Acceleration is caused by a net force acting on an object. This can be a result of pushing, pulling, or gravity.
Positive acceleration, also known as acceleration in the direction of motion, occurs when an object speeds up. Negative acceleration, or deceleration, occurs when an object slows down.
Acceleration can affect an object's motion in different ways, depending on its direction and magnitude. If the acceleration is in the same direction as the velocity, the object will speed up. If the acceleration is in the opposite direction, the object will slow down. If the acceleration is perpendicular to the velocity, the object will change direction but not speed.
