Question

Three particles A, B and C are thrown from the top of a tower with the same speed. A is thrown straight up, B is thrown straight down and C is thrown horizontally. They hit the ground with

A. Equal speed at same time
B. Equal speed one after another
C. Unequal speeds one after another
D. Unequal speed at same time

Answer 1

I believe the answer would have to be B. I'm pretty sure?

this is because the speed of gravity is 9.8 m/s squared so they would each fall at the same speed but since they were thrown different ways, they would hit at different times.
