take g = 9.8 (m/s) /s
u=0
t=55 seconds
v=g*t = 9.8*55 = 539 m/s
this ignores air resistance, which would reduce this figure, typical freefall terminal velocity = 70 m/s
An inclined plane can affect the speed of an object by decreasing it due to friction between the object and the surface of the inclined plane. The steeper the incline, the more the speed will be reduced. Additionally, the length of the inclined plane can influence the object's speed as it may take longer for the object to travel the length, thus affecting its overall speed.
The speed of the object is 5 m/s. Speed is calculated as distance divided by time, so 20 meters/4 seconds = 5 m/s.
The speed of a free falling object after ten seconds from rest is approximately 98 m/s. This speed is achieved due to the acceleration of gravity, which is about 9.8 m/s².
The object will move a total distance of 80 meters, which is calculated by multiplying the speed (10 m/s) by the time (8 seconds).
To calculate the speed of an object, we need to know the distance it travels and the time it takes. If the object is 10m away from you and travels that distance in 2 seconds, we can calculate its speed using the formula: Speed = Distance/Time. In this case, Speed = 10m/2s = 5 m/s.

You travelled at an average speed of 2 metres per second.
The speed of the object is 5 m/s. Speed is calculated as distance divided by time, so 20 meters/4 seconds = 5 m/s.
To find the speed of the plane, you can use the formula: speed = distance/time. In this case, the distance is 395,000 meters and the time is 9,000 seconds. Therefore, the speed is 395,000 meters ÷ 9,000 seconds, which equals approximately 43.89 meters per second.
Assuming you are asking about an object that is placed on an inclined plane and the only forces acting on it are gravity and friction; as the slope of the plane increases, more of gravitational force is applied down the plane and less of the frictional force is applied to the object up the plane. Unless there is no frictional force, until the plane reaches a certain critical slope the gravitational force will not overcome the frictional force and the object will not move, and the average speed for the object will be zero regardless of the slope of the plane (below this critical slope). As the slope increases there is an increase in the net force on the object down the plane which results in a higher acceleration down the plane, and with a higher acceleration it will reach a higher speed and so the average speed of the object down the plane will be higher. So, yes, it can be said that the average speed of an object down an inclined plane is dependant on the slope of the plane. If there are other forces involved, for example a motor, then the average speed will depend on these forces as well as the slope.

The speed of the object would be 3 meters per second (45 meters ÷ 15 seconds).
The speed of a free falling object after ten seconds from rest is approximately 98 m/s. This speed is achieved due to the acceleration of gravity, which is about 9.8 m/s².
The object will move a total distance of 80 meters, which is calculated by multiplying the speed (10 m/s) by the time (8 seconds).
To calculate the speed of an object, we need to know the distance it travels and the time it takes. If the object is 10m away from you and travels that distance in 2 seconds, we can calculate its speed using the formula: Speed = Distance/Time. In this case, Speed = 10m/2s = 5 m/s.
I assume the object starts from rest. The speed will be 16*3 which is 48m/s
395000 meters/9000 seconds is 43.889 meters/second
