What is the displacement of a car in 30 seconds if it is Travelling with a velocity of 150 m s?
THEREFORE THE DISPLACEMENT = 450 M.
How do you find final velocity with 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.
How do you calculate distance when decelerating?
Divide by two times the distance. This is the average deceleration rate. Calculate, as an example, the deceleration required to stop a car in 140 feet if it is traveling 60 mph.
What is the displace ment of a car in 30 s if it is Travelling with a velocity of 15 m s?
Explanation: VELOCITY = DISPLACEMENT /TIME TAKEN. THEREFORE THE DISPLACEMENT = 450 M.
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?
What is the acceleration if the speed and direction is constant?
If the speed and direction of an object is constant, then the acceleration is 0 m/s2. b. The acceleration is the velocity change per time ratio: a = (Velocity Change)/t = (23.5 m/s – 12.1 m/s) / (7.81 s) = 1.46 m/s2. c. The acceleration is the velocity change per time ratio:
How do you calculate acceleration in m/s?
To calculate this, use the first variant of the acceleration formula and replace the known variables: 900 km/h – 1.6 m/s 2 · 2 min. After the necessary unit conversion we arrive at the solution: 250 m/s – 1.6 m/s 2 · 120 s = 250 m/s – 192 m/s = 58 m/s or ~209 km/h.
