A marble rolls off a tabletop 1.15 m high and hits the floor at a point 4 m away from the edge of the table in the horizontal direction,
- t= 0.45 seconds.
- V=2.22m/s
- VT=4.95 m/s
This is further explained below.
<h3>What is its speed when it hits the floor...?</h3>Generally, the equation for motion is mathematically given as
S= ut + 0.5at²
Therefore
y = Voy t + 0.5gt^2
1 = 0.5x 98 x 6²
1=4.9t^2
t= 0.45 seconds.
b) Horizontal motions are uniform.
V=Horizontal displacement/time
V=1/0.45
V=2.22m/s
C)
Vx: 2.22 m/s At bottom,
Vy² = Voy² + 2as
Vy² = 2x95x1
Vy² = 19.6

Answer:
The fraction of the total energy goes into kinetic energy of proton is
Explanation:
Given:
Mass of proton
Mass of electron kg
Here neutron at rest decays into proton and electron
⇄
Where energy released
The value of this reaction is given by
Where kinetic energy of reaction
Here we need to find fraction of the total energy released goes into the kinetic energy of the proton
Therefore, the fraction of the total energy goes into kinetic energy of proton is
