A ball with an initial velocity of 25 ms is subject to an acceleration of 98ms2 how high does it go before coming to a momentary stop class=

Respuesta :

Answer:

The ball will reach an height of 31.88 meters before coming to a stop.

Explanation:

we know that by equation of motion [tex]v^{2} = u^{2} + 2as[/tex]

where v is the final velocity of the ball , u is the initial velocity of the ball , a is acceleration due to gravity and s is the distance traveled by the ball.

a = -9.8 [tex]\frac{m}{s^{2}}[/tex]

and u = 25 m/s

and v = 0

therefore s = [tex]\frac{u^{2}}{2a}[/tex]

so s = 31.88 meters
