How to find magnitude of acceleration?
Rule: Magnitude of acceleration = Change of velocity / Time interval In linear motion, magnitude of acceleration is the measurement of change in speed in speed per unit time. For example: A car reaches a speed of 20 miles per second in 4 seconds, the magnitude of acceleration is 5 miles per second. a = 20 miles/second divided by 4 seconds = 5 miles per second. Acceleration is a vector, which means it has magnitude and direction. To describe accelerated motion completely, the direction also needs to be included. So it would be 5 miles per second in whatever direction it is going.
A car starts from rest and reaches 20 ms in 10 seconds The average acceleration of the car in ms2 is?
10
A ball is dropped off a cliff and reaches a speed of 29.4 meters per second after 3.0 s What is the balls average acceleration?
29.4/3=9.8m/s2
What is the average speed of a car from 0 to 10s?
The average speed of a car from 0 to 10 seconds can be calculated by taking the total distance traveled and dividing it by the total time taken. If the car accelerates uniformly from rest, you can use the formula for average speed, which is the final speed divided by 2. For example, if the car reaches a speed of 20 m/s at 10 seconds, the average speed would be 10 m/s. If more specific details about distance or acceleration are provided, a more precise calculation can be made.
If a skydiver reaches terminal speed after ten seconds will the skydiver gain more speed during the first second or the ninth second?
I would imagine that it is uniform acceleration up until terminal speed. However, wind resistance will be higher 10000 feet up, so acceleration may be less at the start
A 747 airliner reaches its speed of 170 miles per hour in 35.1seconds What is the magnitude of its average acceleration?
2.165 m/s^2

A skydiver steps from a helicopter and falls for 5 seconds before reaching her terminal velocity during this 5 second interval her acceleration?
is constantly decreasing until it reaches zero when she reaches terminal velocity. At that point, her acceleration is zero and she falls at a constant speed, experiencing air resistance equal in magnitude to her weight.
A ball tossed vertically upward rises reaches its highest point and then falls back to its starting point during this time the acceleration is always?
The acceleration is always directed downward due to gravity. At the highest point, the acceleration is still acting downward, but its magnitude is zero as the ball momentarily stops before descending back down.

29.4/3=9.8m/s2
Give example where the velocity of the particle is 0 and acceleration is maximum?
When a pendulum reaches its maximum elongation the velocity is zero and the acceleration is maximum
What is the acceleration due to gravity when a body reaches the ground?
The acceleration is still 9.8 m/s2 but the force applied by gravity is counteracted by the ground.
What is the rate of acceleration for a car that reaches a speed of three meters per second?
Insufficient information.
What happens to an object acceleration as it goes from free fall to terminal velocity?
As an object falls freely, its acceleration remains constant at approximately 9.8 m/s^2 until it reaches terminal velocity. Once it reaches terminal velocity, the acceleration becomes zero as the forces acting on the object balance out, resulting in a constant velocity.
What is the average net force if a car with 1000kg reaches the speed of 28 meters per seconds in 7 seconds?
Acceleration = (change in speed) / (time) = 28/7 = 4 meters per second2Force = (mass) x (acceleration) = (1,000 x 4) = 4,000 kg-m/sec2 = 4,000 Newtons.
When an object reaches its termainal speed its acceleration is zero right?
Yes, when an object reaches its terminal speed, the acceleration becomes zero because the forces acting on the object (such as air resistance) have balanced out the force of gravity causing the object to fall at a constant speed. This constant speed is the terminal speed of the object.
