Los clavadistas de la “quebrada de Acapulco” se lanzan horizontalmente
desde una plataforma rocosa, que está aproximadamente a 35 m sobre el
agua; sin embargo, ellos deben librar protuberancias rocosas al nivel del mar,
que se extienden hasta 5 m desde la base del acantilado directamente debajo
su punto de lanzamiento.
a) ¿Cuánto tiempo permanecen en el aire?
b) ¿Qué rapidez mínima inicial es necesaria para lograrlo?

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.
