If a gandma was traveling on her skateboard at 3.0 m/s, and suddenly jumps backwards off of the skate board, thus kicking the skateboard 7.0 m/s. How fast is grandma going as her feet feet hit the ground? Grandma has a mass 50 kg. and the skateboards mass is 5.5 kg.
A.) 4.1 m/s
B.) 3.5 m/s
C.) 2.6 m/s
If anyone can help me set up the equation correctly I would greatly appreciate it!
