A hockey puck slides off the edge of a horizontal platform with an initial velocity of 28. 0 m/shorizontally in a city where the acceleration due to gravity is 9. 81 m/s2. The puck experiences no significant air resistance as it falls. The height of the platform above the ground is 2. 00 m. What is the angle below the horizontal of the velocity of the puck just before it hits the ground?.

Layer r contains a well-known index fossil that is 100 million years old. based on this information and the principle of superposition, a. layers t and m are older than 100 million years, and layers x and g are younger than 100 million years. b. layers t, m, x, and g are all older than 100 million years. c. layers t and m are younger than 100 million years, and layers x and g are older than 100 million years.
