## What is the final velocity of a car that accelerated 10m s 2 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.

## 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 velocity of the car at the end of 10 seconds?

Explanation: the car was initially at rest so the initial velocity is 0. Thus,the position of car at the end of 10s is 400m far from its initial position. Thus the velocity of the car at the end of 10s is 80m/s 80 m/s.

## What is the ratio of speed to the magnitude of velocity when the body is moving in one direction?

greater than or equal to one. When an object is moving along a straight path, magnitude of velocity is equal to the speed. Therefore, numerical ratio of velocity to speed is one.

## What is the formula for initial velocity?

Let us take a quick look at those formulas. The first formula to find initial velocity is u = v – at.

## What is the acceleration of a car moving at a constant velocity of 30m s?

A car is moving at a constant speed of 30 m/s in a straight line. The acceleration of the car is zero.

## What is the formula for the velocity of a car after collision?

What is the formula of collision? From the conservation of momentum, the formula during a collision is given by: m1v1 + m2v2 = m1v’1 + m2v’2. If the collision is perfectly inelastic, the final velocity of the system is determined using v’ = (m1v1 + m2v2)/m1 + m2.

## What is the acceleration in SI units of car starts from rest and attains a velocity of 18 km h in 2sec?

Final velocity (v) = 18 km/h = (18 * 5 / 18) = 5m/s. Time taken (t) = 2 sec. ⇒ a = 2.5 m/s². Hence, the acceleration acquired by the car is 2.5 m/s².

## What is the formula for uniform acceleration?

The first kinematic equation is v = v 0 + a t , where v is the final velocity, v is the initial velocity, a is the constant acceleration, and t is the time. It is a rearranged expression from the definition of acceleration, a = v − v 0 t .

## 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).

## What is an example of acceleration?

If we look at it in general, acceleration is said to be when an object is increasing its speed cautiously. In other words, it means if you are traveling in a car which is moving at the speed of 60 kmph and after 1 min the speed of the car is 65 kmph, which means you are accelerating.

## 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.

## What is the acceleration of the velocity changes from 45m s to 60m s in three seconds?

Answer. Answer: Acceleration = change of velocity/ time so 60-45/3 so 15/3=5.

## How to find final velocity with acceleration distance and time?

Velocity Equations for these calculations: Final velocity (v) squared equals initial velocity (u) squared plus two times acceleration (a) times displacement (s). Solving for v, final velocity (v) equals the square root of initial velocity (u) squared plus two times acceleration (a) times displacement (s).
