Q. An astronaut in his space suit can throw a ball a maximum distance dmax = 8 m on the surface of the earth.(adsbygoogle = window.adsbygoogle || []).push({});

--------------------------------------------------------------------------------

a) For a given speed of the ball, what angle to the horizontal q (in degrees) will yield the greatest range?

q = ° 45 *

--------------------------------------------------------------------------------

b) If the ball is thrown at this same angle q, what speed will produce this greatest range (8 m) ?

v = m/s *

sqrt (78.48) OK

--------------------------------------------------------------------------------

c) How far can he throw the ball on a planet where g1 = 19 m/s2?

xp = m *

9.81*8/19 OK

--------------------------------------------------------------------------------

d) What height will the ball reach on this "maximum range" trajectory? (on the planet where g1 = 19 m/s2)

hmax = m

3.91 NO

Need help with part d,

I think we need to use the formula , X = V sqrt (2H/g), if yes, what to plug in,

Pl. Help
