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.

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.
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.
