## How long does it take the car to come to a stop?

In an emergency the average driver takes approximately 1.5 seconds to react. A modern vehicle with good brakes and tyres, after braking, is capable of stopping at approximately 7 m/s2. A dry road that is sealed and level enables good friction between the tyres and the road to help stop the vehicle sooner.

## What is the formula for calculating deceleration?

The deceleration will be computed by dividing the final velocity minus the initial velocity, by the amount of time is taken for this drop in velocity. The formula for acceleration can be used here, with a negative sign, to identify the deceleration value.

**What is the car initial velocity?**

5ms−1.

### How long does it take to stop a car going 20 mph?

about 20 feet

Although a car traveling at a speed of 20 mph will take about 20 feet to stop once the driver has pushed the brake pedal, a vehicle going 40 mph will require 80 feet of space to be covered before it ceases moving.

### What is the initial velocity of the car?

**What is the final velocity when a car starts from rest?**

A car starts from rest if its final velocity becomes 20m/s after 10 seconds. What is the acceleration of the car? Acceleration =? Praduryantar =? The velocities for each succeeding time intervals are 2 m/s, 4 m/s, 6 m/s, 8 m/s, 10 m/s, 12 m/s, 14 m/s, 16 m/s, 18 m/s, & 20 m/s respectively. Acceleration =? Praduryantar =?

#### What is the acceleration of a car in m/s?

The answer is (60 mph – 0 mph) / 8s = (26.8224 m/s – 0 m/s) / 8s = 3.3528 m/s 2 (meters per second squared) average acceleration. That would be 27,000 miles per hour squared. That would be 27,000 miles per hour squared.

#### What is the acceleration of a truck traveling at 60 mph?

The answer is (60 mph – 0 mph) / 8s = (26.8224 m/s – 0 m/s) / 8s = 3.3528 m/s 2 (meters per second squared) average acceleration. That would be 27,000 miles per hour squared. Example 2: If a truck is travelling at 50 km/h and increases its velocity to 65 km per hour in 10 seconds, what is its acceleration?

**How do you calculate the acceleration of a vehicle?**

The acceleration of the vehicle is solved using the formula a = (final velocity – initial velocity) / elapsed time. The final velocity is zero since the vehicle stops, the initial velocity is 20 m/s and the elapsed time is 4 seconds. Just plug-in the values in the given formula and do the division yourself.
