Answer to a math question A baseball player throws a 0.2 kg ball upward with a speed of 10 m/s. Calculate the kinetic energy and potential energy of the ball when it reaches its maximum height.
Sea positiva la dirección ascendente.
a máxima altura, velocidad =0. Por tanto, la energía cinética es igual a 0.
también,
a = (vf-vi)/t
-9,8 = (0-10)/t
t = 50/49 s
por eso
d = vi*t +1/2*at²
d = 10*50/49 +1/2*(-9,8)*(50/49)²
re = 5,102 m
por lo tanto, PE=mgh =
0,2*9,8*5,102
PE = 10 J
