Answer:
acceleration = final velocity - initial velocity / time
V-U/T
Explanation:
Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt.
Cathody Ray electrons striking the anode of an x-ray tube increases
First step is to convert the lb to kg as follows:
1 lb = 0.45 kg
Therefore, 150 lb = 150 x 0.45 = 67.5 kg
Avogadro's number = 6.02 x 10^23
Mass of Avogadro's number of people = 6.02 x 10^23 x 67.5
= 4.0635 x 10^25 kg
Answer:
You need to use the equations of motion which I wrote down in the image. Since the runner starts from rest, the initial velocity(v0) is 0 and initial position(x0) is also 0. The solution is in the image attached below.
A) The ball on the small ball is far smaller than the force on the basketball.
B) The total momentum before and after the collision remains constant.
C) We know momentum is conserved so we do:
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
0.1 x 5 + 0.6 x 0 = 0.1 x -4 + 0.6 x v₂
v₂ = 1.5 m/s
