Carese is driving a motorcycle with a constant velocity to the right. Name all four forces (with directions) acting on the motorcycle. Are they balanced or unbalanced? Why?
Brianna and Amiyah used very similar egg drop devices. They had the same mass and same amount and type of padding. Brianna's was in the air for 1.5 seconds and Amiyah's was in the air for 0.8 seconds. Give one possible reason why Brianna's was in the air for a greater period of time AND which student's egg is more likely to survive and why?
Brianna's had a parachute or a gliding design. Brianna's is more likely to survive because it was slower, therefore it hit the ground with less Force.
