What else can I help you with?
Direction of an object's velocity changes uniformly frome east to north What is the direction of acceleration?
North-west. More specifically, as the object's velocity direction changes uniformly from east to north, the acceleration and force producing this acceleration are both constant and changing direction uniformly from north to west.
What does it mean by velocity's reversed direction?
When velocity's direction is reversed, it means that the object is now moving in the opposite direction to its original motion. For example, if an object was initially moving east, reversing its velocity direction would cause it to now move west.
Can an object have velocity and acceleration vectors that point in opposite directions?
Yes it can, and it's really easy. -- A stone tossed upward, before it peaks and starts falling, has upward velocity and downward acceleration. -- A car driving east and slowing for a stop-sign has eastward velocity and westward acceleration.
Speed and direction of motion?
The speed of an object is how fast it is moving, usually measured in units such as meters per second. The direction of motion indicates which way the object is moving, such as north, south, east, or west. Together, speed and direction describe the velocity of the object.
What must be included when reporting an objects velocity-?
When reporting an object's velocity, you must include both the speed of the object and its direction. Velocity is a vector quantity that describes how fast and in which direction an object is moving. This can be represented using units such as meters per second (m/s) or kilometers per hour (km/h) along with a direction (e.g., north, east).
A dog travels 250 meters east in 8 seconds what is the velocity of the dog?
To calculate the velocity of the dog, you divide the distance traveled by the time taken. The dog travels 250 meters east in 8 seconds, so the velocity is 250 meters / 8 seconds = 31.25 meters per second east. Thus, the dog's velocity is 31.25 m/s east.
What is the average velocity of an object that travels 6 meters north in 2 seconds and then travels 3 meters east in 1 second?
3.00 m/s
If an object is moving at unifrom acceleration what is its velocity?
A body moving at a uniform speed may have a uniform velocity, or its velocity could be changing. How could that be? Let's look. The difference between speed and velocity is that velocity is speed with a direction vector associated with it. If a car is going from, say, Cheyenne, Wyoming to the Nebraska state line at a steady speed of 70 miles per hour, its velocity is 70 miles per hour east. Simple and easy. Uniform speed equals uniform velocity. (Yes, I-80 isn't perfectly straight there. Let's not split hairs.) But a car moving around a circular track at a uniform speed is constantly changing direction. Its speed is constant, but its velocity is changing every moment because the directionit is going is changing. Speed is uniform, but velocity isn't. As asked, uniform speed is a uniform distance per unit of time. And this will yield a uniform distance per unit of time in its velocity, but the direction vector may be uniform or it may be changing each moment, as illustrated.
A kangaroo hops 60 meters to the east in 5 seconds what is the velocity?
12m/s east
A Kangaroo hops 60 m to the east in 5 seconds What is the kangaroo's velocity?
It's 60 divided by 5, Which is 12m/s east. Velocity is a vector for speed, since velocity has a direction and speed does not. Velocity has the SI units of meters per second. So you take the meters and divide by how many seconds to get your velocity.
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
What is an objects velocity?
An object's velocity is it's speed plus direction. example: 55mph south Hope this helps:)
Direction of an object's velocity changes uniformly frome east to north What is the direction of acceleration?
North-west. More specifically, as the object's velocity direction changes uniformly from east to north, the acceleration and force producing this acceleration are both constant and changing direction uniformly from north to west.
What does it mean by velocity's reversed direction?
When velocity's direction is reversed, it means that the object is now moving in the opposite direction to its original motion. For example, if an object was initially moving east, reversing its velocity direction would cause it to now move west.
Is there a velocity to the eastern direction to an object which is having a acceleration to the west?
Yes, if it is already moving East but decelerating i.e. accelerating to the west. The other condition when there is velocity to the east while accelerating to the west is when it is moving at an angle to the East-West line.
A car travels 4500m east in 5 seconds what is the cars average velocity?
900 m/s velocity=meters/sec v=4500/5=900
How do you find velocity with a known time and distance?
Velocity equal distance divided by time. For example, an object that traveled 5 metes in 10 seconds had a velocity of 5/10 meters per second which is .5 meters per second. Velocity is speed in a direction. Sometimes a navigate or positive number is sufficient as the direction. Other times you will need to be more specific, such as .5 meters per second East or 1.3 meters per second 30 degrees East of North.
