If a small lead ball falls from a high tower on Earth what will be its velocity after 2 seconds?
v = a X t. a = 9.8 m/s2 (acceleration) and t = time. At t = 2 seconds, v = (9.8 m/s2) X (2 s) = 19.8 m/s. At t = 4 seconds, v = (9.8 m/s2) X (4 s) = 39.6 m/s. [ANSWER: at t = 2 s, v = 19.8 m/s ; at t = 4 s, v = 39.6 m/s. ]
How do you calculate acceleration on a lift?
Acceleration on a lift can be calculated by dividing the change in velocity by the time taken. For example, if the lift starts from rest and accelerates to a velocity of 4 m/s in 2 seconds, the acceleration would be (4 m/s - 0 m/s) / 2 s = 2 m/s^2.
A horses velocity changes from 0 m s to 10 m s 5 seconds later What is the horses average acceleration?
The horse's average acceleration can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. Plugging in the values, we get: acceleration = (10 m/s - 0 m/s) / 5 s = 2 m/s^2. Therefore, the horse's average acceleration is 2 m/s^2.
A car traveling at a velocity of 24 ms is accelerated uniformly at a rate of 2 ms2 for 8 seconds what is the final velocity?
The final velocity can be calculated using the formula: final velocity = initial velocity + (acceleration * time). Given the initial velocity of 24 m/s, acceleration of 2 m/s^2, and time of 8 seconds, you can substitute these values into the formula to find the final velocity. Final velocity = 24 m/s + (2 m/s^2 * 8 s) = 24 m/s + 16 m/s = 40 m/s. Therefore, the final velocity of the car is 40 m/s.
A car traveling at a velocity of 24 m s is accelerated uniformly at a rate of 2 m s for 8 seconds what is the final velocity of the car?
The final velocity can be calculated using the formula: final velocity = initial velocity + acceleration × time. Given: initial velocity = 24 m/s, acceleration = 2 m/s², and time = 8 seconds. Plugging in the values: final velocity = 24 m/s + 2 m/s² × 8 s = 24 m/s + 16 m/s = 40 m/s. Therefore, the final velocity of the car is 40 m/s.
How to find the side of the square with an area of 256m squared?
A = s^2 256 m^2 = s^2 √(256 m^2) = √(s^2) 16 m = s Thus, the side of the square has a length measure of 16 m.
What is the unit of E in E equals mc2?
Units Units of 'E' are kg m^2 s^-2 or kg(m/s)^2 or kg m^2 / s^2 or kg m ( m/s^2) In words it is a mass(kg) multiplied to distance (m) multiplied to acceleration (ms^-2). When Basic S.I. units are arranged in this manner they are referred to a Joules.

Acceleration of gravity in meters per square second?
9.80665 m/s^2 Depending on where you are on the earth's surface the acceleration of gravity can vary by about 0.1 m/s^2. The average on earth though is taken to be 9.80665, in physics calculations 9.81 m/s^2, 9.8 m/s^2, or even 10 m/s^2 are often used. Note: 10 m/s^2 is actually a fairly good approximation and can speed up calculations significantly.

The horse's average acceleration can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. Plugging in the values, we get: acceleration = (10 m/s - 0 m/s) / 5 s = 2 m/s^2. Therefore, the horse's average acceleration is 2 m/s^2.

A car traveling at a velocity of 24 ms is accelerated uniformly at a rate of 2 ms2 for 8 seconds what is the final velocity?
The final velocity can be calculated using the formula: final velocity = initial velocity + (acceleration * time). Given the initial velocity of 24 m/s, acceleration of 2 m/s^2, and time of 8 seconds, you can substitute these values into the formula to find the final velocity. Final velocity = 24 m/s + (2 m/s^2 * 8 s) = 24 m/s + 16 m/s = 40 m/s. Therefore, the final velocity of the car is 40 m/s.
When walking to school you approach an intersection and slow down from 2 m s to a stop in 3 s What is your acceleration during this time interval?
Acceleration is change in velocity over time. In the metric system it is measured in meters per second per second (m/s squared). To figure it out, subtract the initial speed from the final speed and divide the difference by the time. In your example, 0 m/s - 2 m/s = -2 m/s. -2 m/s divided by 3 s = -2/3 m/s squared. Because the answer is a negative number, it is a deceleration - a slowing down.
A car traveling at a velocity of 24 m s is accelerated uniformly at a rate of 2 m s for 8 seconds what is the final velocity of the car?
The final velocity can be calculated using the formula: final velocity = initial velocity + acceleration × time. Given: initial velocity = 24 m/s, acceleration = 2 m/s², and time = 8 seconds. Plugging in the values: final velocity = 24 m/s + 2 m/s² × 8 s = 24 m/s + 16 m/s = 40 m/s. Therefore, the final velocity of the car is 40 m/s.
What is the acceleration of a car that slows down from 60 ms to 40 ms during a period of 10 seconds?
The acceleration of the car can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. Plugging in the values: acceleration = (40 m/s - 60 m/s) / 10 s = -2 m/s^2. The negative sign indicates that the car is decelerating.
If you know an object's mass and acceleration you can determine the net force being exerted on the object true or false?
This is true. Newton's 2nd law gives us the equation F_net = ma, where m is mass in kilograms and a is acceleration in m/s/s (also m/s^2). 1 kg m/s^2 = 1 Newton (N).Example: What is the net force if a 6.0 kg mass is accelerated at 4.0 m/s^2?Answer: F_net = ma = 6.0 kg x 4.0 m/s^2 = 24 kg m/s^2 = 24 N
