Question

A science student is riding on a flatcar of a train traveling along a stralght horizontal track at a constant speed of 12.0 m/s. The student throws a ball into the alr along a path that he judges to make an initial angle of 50.0 with the horizontal and to be in line with the track. The student's professor, who is standing on the ground nearby, observes the ball to rise vertically. How high does she see the ball rise? -2 points PSE5 4.P.049. My Notes A ball on the end of a string is whirled around in a horizontal circle of radius 0.332 m. The plane of the circle is 1.00 m above the ground. The string breaks and the ball lands 2.20 m (horizontally) away from the point on Lhe ground directly berneath the ball's loation whe the tring breaks. Firnd the raclial acceleration of the ball during its circular motion Magnitude m/s Direction O toward the center of curvature Oaway frorm Lhe center of curvalure
