if a golf ball and a ping-pong ball both move with the same kinetic energy, which has the greater speed?

answer would be d.) i hope this

explanation:

momentum of soft ball three times less than baskey ball

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
