A ball is thrown upwards with a speed 11 m/s at an angle of 52o above horizontal. How much time before it reaches the top of its flight? Answer in seconds.

Neglect air friction and use g = 9.8 m/s2 if needed. Pay attention to the way the angle is defined.

    A ball is thrown upwards with a speed of 19 m/s. it reaches a hight of 18.4 m above the point of release before it falls back down. Specify down as the positive direction and the initial position as the origin. If the balls position after three seconds is -12.9 meters, what is the distance traveled by the rock? The acceleration due to gravity is 9.8 m/s^2 down. The answer is 23.9 meters, how would i solve this?
