Trebuchets are widely recognized to be the superior siege engine. During the launching process a 90 kg stone begins on the ground and leaves the trebuchet 15.0 m above the ground moving at a speed of 35.0 m/s. If an average power of 30 kilowatts is exerted on the stone during the launch, how long is the launch in seconds? (Consider the force to always be in the direction of the stone's motion such...

0.94 Question 1 pts Trebuchets are widely recognized to be the superior siege engine. While launching its payload, the trebuchet moves a 90 kg stone a total of 25.0 m. The stone leaves the trebuchet 15.0 m above the ground where it was initially at rest. If the trebuchet can exert an average force of 2500 N on the stone during launch, how fast is the 90 kg stone moving as it is released in m/s? (Consider the force to...
