simile said:equals 500
Not sure where you are getting 500 from, but my guess is that either it should say 1000m in the OP or in the above you meant 50.simile said:i basically equalled both equations to 500. then i integrated to find when the displacement equals 500. Then i subbed the time back into v equations. After i added the velocity together ,and divided 500/speed.
Velocity is a measure of an object's speed and direction. It is a vector quantity, meaning it has both magnitude (speed) and direction. In physics, velocity is often denoted as "v" and is measured in meters per second (m/s).
Velocity is calculated by dividing the change in an object's position by the change in time. This is represented by the equation v = (xf - xi)/t, where v is velocity, xf is final position, xi is initial position, and t is time.
Velocity and speed are often used interchangeably, but they have different meanings in physics. Speed is a measure of how fast an object is moving, while velocity also takes into account the direction of motion.
Yes, velocity can be negative. A negative velocity indicates that an object is moving in the opposite direction of its positive velocity. For example, if an object is moving to the left with a velocity of 5 m/s, a negative velocity of -5 m/s would indicate that the object is now moving to the right.
When two particles collide, their velocities can change depending on the type of collision. In an elastic collision, both particles will bounce off each other with the same speed and opposite directions. In an inelastic collision, the particles will stick together and move off with a combined velocity. The change in velocities can be calculated using the laws of conservation of momentum and energy.
