3. 0/2 points| Previous Answers PSE6 4.P.045. My Notes A science student is riding on a flatcar of a train traveling along a straight horizontal track at a constant speed of 8.00 m/s. The student throws a ball into the air 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? 1.814207 Your response differs from the correct answer by more than 10%. Double check your calculations. m Submit Answer Save Progress Practice Another Version

Answer 1

maximum height reached = u^2 sin^2 a / 2g

where u = initial velocity

a = angle of incline

g = acceleration due to gravity

H = 8^2* (sin 50)^2 / 2*9.8

= 1.9161 m

so the maximum height is 1.9161 m
