Since the acceleration is uniform you can add the starting and ending velocities and divide by two the average speed
145 + 73 = 218
218/2 = 109 (units not given so I assume Miles per Hour)
To convert to Feet per seconds
109 mph X 5280 feet in a mile / 3600 seconds in an hour = 159.866667 feet per second
multiply the above by 15 seconds and you get 2398 feet
Velocity is the rate of speed in a given direction. Therefore, the plane's velocity is 610mph NW.
A negative acceleration has the affect of decreasing the velocity of the moving object.If a plane is climbing at a speed of 100 meters per second and is subject to an acceleration of -20 meters per sec2 then after 1 second it's climbing speed will reduce to 80 mps, after 2 seconds to 60 mps .....and so on.This is illustrated by the law of motion v = u + ft, where u is the initial velocity, v is the final velocity, f is the acceleration and t is the time.How long does it take the plane to reach a zero climbing velocity.v = u + ft : 0 = 100 -20t : 20t = 100 : t = 5 seconds, which can be easily verified from the example a few lines above.
The resultant velocity of a plane is 75 km/hr.
gravity of earth is constant in any plane but the acceleration may vary becoz of irregular plane
Yes it does ! Even if both bullets are identical and fired from the same make of gun, the one in the plane will already have the velocity the plane is travelling at before it's fired.
changing the slope of the inclined plane changes the values for velocity because of the unbalanced external force exerted on the object increases the velocity.
changing the slope of the inclined plane changes the values for velocity because of the unbalanced external force exerted on the object increases the velocity.
To calculate the distance traveled while the velocity is increasing, you can use the formula: distance = initial velocity * time + 0.5 * acceleration * time^2. In this case, the initial velocity is 75 m/s, the final velocity is 145 m/s, the acceleration is constant, and the time is 15 seconds. Plugging these values into the formula will give you the distance the plane travels during the acceleration period.
Increasing the slope of the inclined plane will increase the velocity of an object sliding down it due to gravity pulling the object downward with more force. The acceleration of the object will also increase because there will be a larger component of the force of gravity acting to accelerate the object down the slope.
Velocity of an object is the speed of the object and the direction of its motion. However, acceleration is the change in velocity divided by time it takes for the change to occur.Velocity is describing how an object in a 2+ dimensional plane is changing its position with 1 or 2 dimensional time.ANSWERAcceleration is describing how an object changes its velocity with time.Velocity is defined as Displacement of a body in a particular time.Velocity = Displacement/Time. Whereas Acceleration of a body is defined as change in Velocity of a body at a particular instant of Time.Acceleration = Final Velocity-Initial Velocity/TimeNow If Velocity is Uniform or Constant then Acceleration is ZeroThe same difference as between velocity and position.Velocity is the change of position per time unit.Acceleration is the change of velocity per time unit. If an object, for example, goes faster and faster (or slower and slower), then it is accelerating.The difference is that velocity refers to the speed of something while acceleration refers to the increase of that speed. For example you step on the accelerator to increase the velocity (speed) of your car.Acceleration means, how fast is the velocity changing. Velocity is speed with a direction.Velocity is the distance covered over time; acceleration is the variation in velocity over a period of time.
use a uniform acceleration equation, Δx = ½ (Vi + Vf) Δt where displacement = 1/2 (initial velocity + final velocity) time displacement = 1/2 (59 m/s + 78 m/s) * 12s displacement = 822 m

To find the distance traveled, we can use the formula: distance = initial velocity * time + 0.5 * acceleration * time^2. The initial velocity is 75 miles per second, the final velocity is 145 miles per second, and the time is 15 seconds. The acceleration can be found using the formula: acceleration = (final velocity - initial velocity) / time. Plug in the values to find the acceleration and then calculate the distance traveled in 15 seconds.
To find the distance the plane travels, you can use the average velocity formula, which is the sum of initial velocity and final velocity divided by 2, and then multiply by the time. Average velocity = (75 m/s + 145 m/s) / 2 = 110 m/s Distance traveled = (110 m/s) * 15 s = 1650 meters

The acceleration of a tennis ball rolling down an incline depends with two factors. The force that is applied to the tennis ball and the mass of the tennis ball will determine its acceleration.
Either of these is referred to as positive acceleration: A) the object's velocity is increasing in the frame of reference B) the object is being moved in a positive direction in a coordinate plane
