## What is acceleration A car starting from rest acquires a velocity of 54 km per hour in 5 seconds calculate its acceleration?

Hence, the acceleration of the car is 7.5 m/s².

**What is its velocity after 3 seconds of deceleration?**

After 3 seconds, the velocity is 4.5+3×1.5=9 m/s.

### What is the acceleration of a car which started from rest and acquired a velocity of 45 m/s in 5 s?

a=5m/s^2.

**What will be the acceleration of a car if it shows from 90 km/h to a stop in 10 sec?**

Question 1: What will be the Acceleration of a Car if it Slows from 90 kmph to a Stop in 10 sec? Answer: Here, u = 90 kmph = 90 x 5/18 = 25 m/s because initially it was moving at a speed of 90 kmph then reached zero.

#### How do you find velocity 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.

**How do you find velocity with distance and deceleration?**

Square the initial speed and the final speed. Subtract the square of the final speed from the square of the initial speed. Divide by two times the distance. This is the average deceleration rate.

## What is the average acceleration of a car in 8 seconds?

Example 1: If your car starts at 0 mph and accelerates to 60 miles per hour in 8 seconds, what is its average acceleration during these eight seconds? 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.

**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?

### Will a car with a constant velocity experience acceleration on a track?

Question 3: A Car Moves in a Circular Track with a Constant Velocity; will it Experience Acceleration? Answer: Here, the speed is constant; however, the direction is continuously varying, which means the velocity is also varying. It states that the car will experience acceleration.

**How do you find acceleration with velocity and time taken?**

The acceleration ‘a’ is given as: a = Change in velocity/Time Taken This formula states that the rate of change in velocity is the acceleration, or if the velocity of an object changes from its initial value ‘u’ to the final value ‘v’, then the expression can be simply written as: a = (v – u)/t
