In order for a 40-kg mass to accelerate at 2 meters/sec2 , a force
of (40 x 2) = 80 newtons has to come from somewhere.
That force is what produces that acceleration.
The student's velocity is 4 meters per second. Velocity is calculated by dividing the distance traveled by the time taken. In this case, 20 meters divided by 5 seconds equals 4 meters per second.
Newton's third law of motion states that for every action, there is an equal and opposite reaction. This means that when one object exerts a force on a second object, the second object exerts an equal force in the opposite direction on the first object.
The acceleration due to gravity alone on Earth is about 9.81 meters per second-squared.
"Meters" is not a unit of acceleration.The acceleration of gravity on or near the surface of the Earth is about9.8 meters/second2 .It's different in other places.
The average acceleration can be calculated using the formula: acceleration = (change in velocity) / (time taken). In this case, the change in velocity is 20 m/s - 16 m/s = 4 m/s and the distance is 36 meters. Since time is not provided, the acceleration cannot be determined.
That's easy, if the car is initially traveling at 25 meters per second and gradually accelerates 3 meters per second for 6 seconds then the car is traveling at 43 meters per second.
gravity
3 m/s2
The acceleration of the body is 3 m/s²
6 meters per second. Explanation: After 1 second = 2 meters per second. After 2 seconds = 4 meters per second. After 3 seconds = 6 meters per second.
60.912 meters in that time
If the acceleration was constant (15 + 25) /2 = 20 (time does not figure into the averaging at all!)
Acceleration cannot be measured in metres per second. There is, therefore a fundamental problem with the question.
The mass of an object can be determined by taking (the net force in Newtons) divided by (the acceleration in meters per second per second).
The student's velocity is 4 meters per second. Velocity is calculated by dividing the distance traveled by the time taken. In this case, 20 meters divided by 5 seconds equals 4 meters per second.
The acceleration due to gravity on Earth is approximately 9.81 meters per second squared (m/s^2). This value represents the rate at which an object accelerates towards the Earth when in free fall.
Meters per second squared (m/s²) measures acceleration, which is the rate of change of velocity per unit time. It indicates how quickly an object's speed is increasing or decreasing. For example, if an object accelerates at a rate of 5 m/s², its velocity increases by 5 meters per second for every second that passes.
