If the velocity of a body changes from 13 ms to 30 ms while undergoing constant acceleration what's the average velocity of the body?
The average velocity of the body is (13 m/s + 30 m/s) / 2 = 21.5 m/s.
When a ball is traveling at a constant velocity of 50 ms and has been traveling for over 2 minutes what is the balls acceleration?
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.
30 s to go from 7 ms to 54 ms What is its acceleration?
The acceleration can be calculated using the formula: acceleration = change in velocity / time taken. Change in velocity = (54 ms - 7 ms) = 47 ms. Time taken = 30 s. Acceleration = 47 ms / 30 s = 1.57 m/s².
What is the formula for time if the given is in acceleration and velocity?
You need velocity at two points in time, and the acceleration must be constant. If the initial velocity is u ms-1 and the final velocity is v ms-1, and the time interval is t then t = (v - u)/a s.
The velocity of a car changes from 10 ms to the east to 30 ms to the east in 4 seconds What is the acceleration of the car?
Average acceleration = (amount of change in speed velocity) / (time for the change) = (30 - 10) / (4) = 5 meters per second2 to the east
If a cars velocity changes from 0 ms to 30 ms 10 seconds later its average acceleration is?
Acceleration = (change in speed) / (change in time) = (30 m/s) / (10 sec) = 3 meters per second2
Boy is pushing a 30 kg box across the floor at a constant velocity of 0.5 ms. How much work in Joules is done by the boy on the box if the velocity change to 1.0 ms?
The work done is zero because the velocity is constant. Work is only done when there is a change in velocity.
You increase your walking speed from 1 ms to 3 ms in a period of 1 s. What is your acceleration?
The acceleration is calculated using the formula: acceleration = (final velocity - initial velocity) / time taken. In this case, the acceleration would be (3 ms - 1 ms) / 1 s = 2 ms^2.
A car traveling in a straight line has a velocity of 5.0 ms After an acceleration of 0.75 ms squared the cars velocity is 8.0 ms In what time interval did the acceleration occur?
4.0 s
What object moving at 30 ms takes 5 s to come to a stop what is the objects acceleration?
The acceleration of the object can be calculated using the formula: acceleration = (final velocity - initial velocity) / time Given that the final velocity is 0 m/s (since the object comes to a stop), the initial velocity is 30 m/s, and the time is 5 s, the acceleration can be found by plugging these values into the formula.
What is the only factor needed to calculate change in velocity due to acceleration of gravity (9.8 ms)?
What is the only factor needed to calculate change in velocity due to acceleration of gravity 9.8 ms?
The rate at which an object changes velocity and or directions?
Acceleration is the rate of change in velocity. (Velocity is speed+direction, it is a vector as well as acceleration). F=ma, where a is in ms^(-2).
