# What is the initial velocity of the car? 5ms−1.

## What is initial velocity and its formula?

The initial velocity,vi is the velocity of the object before acceleration causes a change. After accelerating for some amount of time, the new velocity is the final velocity, vf. initial velocity = final velocity - (acceleration×time) vi = vf - at. vi = initial velocity (m/s)

## What is the velocity of a car?

The standard unit of velocity magnitude (also known as speed ) is the meter per second (m/s). ... If you are driving the car, the velocity of the car relative to your body is zero. If you stand by the side of the road, the velocity of the car relative to you is 20 m/s northward.

## What is the initial velocity of a car which is stopped?

We know v = u +at. Then u = v - at. u = 0 - (-2.5 X 10) = 25 m/s. So initial velocity of the body is 25 m/s.

## What is initial velocity?

Therefore, the initial velocity is the velocity of the object before the effect of acceleration, which causes the change. After accelerating the object for some amount of time, the velocity will be the final velocity.

## How do you find initial velocity and final velocity?

Final velocity (v) of an object equals initial velocity (u) of that object plus acceleration (a) of the object times the elapsed time (t) from u to v. Use standard gravity, a = 9.80665 m/s2, for equations involving the Earth's gravitational force as the acceleration rate of an object.

## What is initial velocity symbol?

The symbol v0 [vee nought] is called the initial velocity or the velocity a time t = 0. It is often thought of as the "first velocity" but this is a rather naive way to describe it.

## How is initial velocity represented?

Initial Velocity is the velocity at time interval t = 0 and it is represented by u. It is the velocity at which the motion starts.

## What is the velocity of car 2 relative to car 1?

So, the relative velocity of car 1 w.r.t car 2 is: 65.192 km/hr. The angle can be found as, .

## What do we mean by velocity?

noun, plural ve·loc·i·ties. rapidity of motion or operation; swiftness; speed: a high wind velocity. Mechanics. the time rate of change of position of a body in a specified direction. the rate of speed with which something happens; rapidity of action or reaction.

## What is velocity short answer?

The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion (e.g. 60 km/h to the north).

## What is the initial velocity of a car which is stopped in 10 seconds?

The initial velocity of the car is 5 m/s and after 10 seconds its velocity becomes 25 m/s.

## Is velocity a speed?

Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement. ... For example, 50 km/hr (31 mph) describes the speed at which a car is traveling along a road, while 50 km/hr west describes the velocity at which it is traveling.

## How do you find final velocity?

Final Velocity Formula

vf=vi+aΔt. For a given initial velocity of an object, you can multiply the acceleration due to a force by the time the force is applied and add it to the initial velocity to get the final velocity.
