Average speed = (50 / 2) = 25 rev per min
Initial speed = 0
Final speed = 50 rev per min
Average acceleration = (50 / 2) = 25 rev per min2
If the ball is traveling at a constant velocity of 50 m/s, then its acceleration is 0 m/s^2. Acceleration is the rate of change of velocity, so if the velocity is constant, there is no change in velocity, and therefore no acceleration.
Oh, dude, acceleration is the rate of change of velocity, not the actual velocity itself. Since the object is traveling at a constant velocity, its acceleration is zero. So, like, it's not speeding up or slowing down, just cruising along at a cool 12 miles per hour west for those 15 minutes.
Since the phonograph record rotates at 33.3 revolutions per minute (rpm), then the revolutions that it turns in 5 minutes is 5*33.3. This is a total of 166.5 revolutions.
To find Ashley's constant speed, you would need to know the distance she traveled during the first 4 minutes of her trip. You can then divide this distance by 4 minutes to calculate her speed. Without the distance traveled, her constant speed cannot be determined.
The average velocity is trying to find how fast the car is going at an average rate. However, constant velocity means that the car is going at an unchanged velocity. Say a car is going at 75 m/s and then changes to 50 m/s and then changes to 25 m/s in 30 minutes. The car is going at different velocities at different times. To find the average, you simply just add the 3 together, then divide by 3 giving you, 50 m/s In the 30 minutes, it's average velocity was 50 m/s However, for a car going at a constant velocity, it means that the velocity never changes. Say a car is going at a constant velocity for 30 minutes at 50 m/s. In those 30 minutes, the car will never change it's velocity and remain at 50 m/s. Constant means that it doesn't change.
The acceleration of the body was zero during this interval because its velocity was constant. Acceleration is the rate of change of velocity, so if the velocity does not change, the acceleration is zero.
If the ball is traveling at a constant velocity of 50 m/s, then its acceleration is 0 m/s^2. Acceleration is the rate of change of velocity, so if the velocity is constant, there is no change in velocity, and therefore no acceleration.
If an object is traveling at a constant velocity, its acceleration is 0. Even if it traveled for 2 years.
1). If neither speed nor direction are changing, then acceleration is zero.2). "minutes" is not a unit of velocity, but we get the idea

Constant speed (in a straight line) means there is no acceleration.Constant speed (in a straight line) means there is no acceleration.Constant speed (in a straight line) means there is no acceleration.Constant speed (in a straight line) means there is no acceleration.
As long as the 30 minute are spent driving in a straight line, the acceleration is zero.
Since the phonograph record rotates at 33.3 revolutions per minute (rpm), then the revolutions that it turns in 5 minutes is 5*33.3. This is a total of 166.5 revolutions.
zero - it is constat velocity. so acceleration is zero50 m/s2 Another : The acceleration is ZERO. Acceleration is defined as the change in velocity per unit time. If the ball is traveling a constant velocity over a two minute period, the acceleration would be zero since there is no change in velocity.
