A glider is an aircraft with no engine. To be launched, a glider is uniformly accelerated from rest by a cable pulled by a motor that exerts a horizontal force on the glider throughout the launch.
The glider reaches its launch speed of 27.0 m/s after accelerating for 11.0 s. Assume that the glider moves horizontally until it leaves the ground. Calculate the total distance travelled by the glider before it leaves the ground. Show Working

Answer:The graph shows the variation with time t of the speed v of a ball of mass 0.50 kg, that has been released from rest above the Earth’s surface.
The graph shows the variation with time t of the speed v of a ball of mass 0.50 kg, that has been released from rest above the Earth’s surface.The force of air resistance is not negligible. Assume that the acceleration of free fall is g = 9.81ms−2.

Answer:
Graph shows variation with time of speed of ball of mass 0.50 kg.
Explanation:
As we know from the question graph shows variation with time speed of a ball of mass 0.50 kg, It has been released from above the earth surface.
And the force of air resistance is not negligible. We can assume acceleration
Of free fall g = 9.81ms-2.
It states that without any calculations, how graph could be used to determine
distance fallen.
It also shows in space below draw and also the label arrows to represent the
Forces on ball 2.0 s.
