1. An astronaut on a strange planet finds that she can jump a maximum horizental distance of 30 m if her initial speed is 9m/s. What is the acceleration of gravity on the planet?
2. A projectile is fired in such a way that its horizental range is equal to three times its maximum height. What is the angle of projection?
thanks
