# What was the acceleration of the car moving initially at 30 m s comes gradually to a stop in 900 m?

## What was the acceleration of the car moving initially at 30 m s comes gradually to a stop in 900 m?

Expert-Verified Answer. The acceleration of the car is 0.5 meters per seconds square. Given the following data: Initial velocity, U = 30 m/s.

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

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 time in acceleration?

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).

## What happens to the velocity of a car when it accelerates?

In everyday conversation, to accelerate means to speed up. The accelerator in a car can in fact cause it to speed up. The greater the acceleration, the greater the change in velocity over a given time. The formal definition of acceleration is consistent with these notions, but more inclusive.

## What is the acceleration of a motor car travelling at 30 metre per second on a circular road of radius 500 m?

ac=v2rac=30×30500=95=1.8m/s2at=2m/s2anet=√(1.8)2+(2)2=√7.24=2.7m/s2.

## What is the acceleration when an object slows down over time?

If acceleration points in the same direction as the velocity, the object will be speeding up. And if the acceleration points in the opposite direction of the velocity, the object will be slowing down.

## 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.

## Is constant acceleration and uniform acceleration same?

Flexi Says: Uniform acceleration and constant acceleration refer to the same thing: a situation in which an object’s acceleration does not change over time.

## Is velocity zero when acceleration is constant?

No, constant acceleration does not mean zero velocity. Acceleration depends on change in velocity. So if velocity is not getting change acceleration will not get change.

## What is the SI unit for acceleration?

the SI unit of acceleration is m / s 2 (meter per sec square)

## What is acceleration time called?

It is called a jerk. It is acceleration/ time. = (M/s²)/s. = (M/s²)×(1/s)

## 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 acceleration of a car that goes from 0 to 60 in 5 seconds?

Explanation: 0 to 60 miles per hour means 0 to 88 feet/sec in five seconds (60 multiplied by 5280 (feet in one mile) divided by 3600 (seconds in an hour). Hence acceleration is 17.6 feet / second ^2.

## What is the acceleration of a car that starts from rest and travels 100 m in 5 s?

Hence, the value of acceleration is 8 m s – 2 . (b) A body starting from rest travels with uniform acceleration. If it travels 100 m in 5 s, what is the value of acceleration?

## What is the acceleration of a car that goes from 30 miles per hour to 60 mph in six seconds?

A car goes from 30 miles per hour to 60 mph in 6 seconds. What is the acceleration of the car? 60-30 divided by 6= 30 divided by 6 = 5 mph squared.

## What is the acceleration of a car when it starts from rest its velocity becomes 20ms 1 in 8s?

a= 2.5m/s² Hope this helps you.
