You’re 6.0 m from one wall of the house seen in the attached image, You want to toss a ball to your friend who is 6.0 m from the opposite
wall. The throw and catch each occur 1.0 m above the ground.
a. What minimum speed will allow the ball to clear the roof?
b. At what angle should you toss the ball?

What happens in a global convection cell

Apebble is thrown into a calm lake, ripples are formed from the center and move outward. the water particles in the lake travel in a circular pattern that moves up and down on the surface of a lake, and the energy travels a) diagonally. b) downward. c) horizontally. d) upward.

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.
