# What is the final velocity of a car that accelerated 10 m s2 from rest and traveled 180m?

## What is the final velocity of a car that accelerated 10 m s2 from rest and traveled 180m?

What is the final velocity of a car that accelerated 10 m/s2 from rest and traveled 180m? V2=u2+2ad=zero2+2*10*180, v2=3600, so v=60 m/s.

## What is the increase in velocity in 2 seconds of a car accelerates at the rate of 5 m per second?

Increase in velocity = acceleration × time =(5×2)ms−1=10ms−1.

## What is the formula for final velocity of acceleration?

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 the formula for velocity increase?

Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.

## What is the formula for displacement?

S = ut + ½ at2 Hence, displacement (s) of an object is equal to initial velocity(u) times time (t), plus half of the acceleration (½ a) multiplied by time squared (t2).

## Does velocity change when acceleration increases?

Sure, as long as acceleration is positive, velocity increases, even if acceleration is decreasing (as long as it doesn’t reach zero). Likewise, as long as acceleration is negative, velocity decreases even if acceleration is increasing.

## Is velocity same as speed?

Why is it incorrect to use the terms speed and velocity interchangeably? The reason is simple. 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. Put another way, speed is a scalar value, while velocity is a vector.

## What is the final velocity?

On the other hand, the final velocity is a vector quantity that measures the speed and direction of a moving body after it has reached its maximum acceleration.

## What is the SI unit for velocity?

What is the SI unit of velocity? The SI unit of velocity is metres per second (m/s). Alternatively, the velocity magnitude can also be expressed in centimetres per second (cm/s).

## When a car starts from rest and attains a velocity of 10 meters per second in 40 seconds?

Expert-Verified Answer A driver starts the car from rest and attains a velocity of 10m/s in 40s and applies breaks and slows down the car to 5m/s in 10s. We have to find the acceleration of the car in both cases. Hence, the acceleration of the car in both cases is 0.25 m/s²and -0.5 m/s².

## What is the final velocity of a car?

The final velocity (v) of an object equals the initial velocity (u) of that object plus acceleration (a) of the object times the elapsed time (t) from u to v.

## What does the acceleration of a moving vehicle is 10m s2 mean?

Answer: cceleration is the rate of change of velocity of a body w.r.t time. Thus, if the acceleration of a body is 10m/s^2 , it means that the body accelerates after every second with a velocity of 10m/s.

⇒⇒ u = 25 m/s.
