Average acceleration = (amount of change in speed velocity) / (time for the change) =
(30 - 10) / (4) = 5 meters per second2 to the east
5 m/s2 east
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.
It has negative acceleration east or positive acceleration west. West
Yes, it is possible. If a body is moving towards east with decreasing velocity, it has retardation or negative acceleration in opposite direction of velocity that is in the direction of west.
12m/s east
Yes.
acceleration is the change in velocity by change in time (often meters/second/second). so, if a car was travelling 10m/s and ten seconds later, it is travelling 20m/s in the same direction, the acceleration would be (20m/s-10m/s)/10s=1m/s/s. with a constant velocity the change in velocity is zero (x m/s - x m/s)/y s=0m/s/s and acceleration is also zero.
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.
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.
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.
If you accelerate an object in one direction the velocity is in the same direction; however if it alraedy had an itial velocity that may not be true. V = vo + at For example if moving with initial velocity to the East and accelerated to the west, it will slow down but still move east for a time
Sure. That's exactly what happens every time you're driving east and you put on the brakes.
