My very eager mother just served us nine pizzas
Explanation:
Mass of the ball, m = 0.058 kg
Initial speed of the ball, u = 11 m/s
Final speed of the ball, v = -11 m/s (negative as it rebounds)
Time, t = 2.1 s
(a) Let F is the average force exerted on the wall. It is given by :


F = 0.607 N
(b) Area of wall, 
Let P is the average pressure on that area. It is given by :


P = 0.202 Pa
Hence, this is the required solution.
That is the answer to the question
I hope this helps you.
Thank you for your question
Answer:
If you put in too much helium, and the pressure inside the balloon exceeds the atmospheric pressure on the outside of the balloon, the balloon will burst.
Explanation:
Welcome! I'm just starting out
Let's choose the "east" direction as positive x-direction. The new velocity of the jet is the vector sum of two velocities: the initial velocity of the jet, which is
along the x-direction
in a direction
north of east.
To find the resultant, we must resolve both vectors on the x- and y- axis:




So, the components of the resultant velocity in the two directions are


So the new speed of the aircraft is:
