Answer:
M = 1073 Mev/c2
u = 0.95 C
Explanation:
given data:
m1 =135 Mev/c2
v1 = 0.53 c
m2 = 938 Mev/c2
v2 = 0.98 c
from conservation of momentum principle we have


...............1
Total mass of INITIAL particle M =m1+m2 = 1073 Mev/c2
using equation 1

solving for u we get
u = 0.95 C
Answer:
Potential Energy stored = mgh ; m : mass, g : gravitational acceleration (let 10m/s) , h : height
Hence,
Energy Stored in the ball = mgh = (2*10*4) J
= 80 Joules!
Answer:

Explanation:
<u>Vertical Launch Upwards</u>
In a vertical launch upwards, an object is launched vertically up from a height H without taking into consideration any kind of friction with the air.
If vo is the initial speed and g is the acceleration of gravity, the maximum height reached by the object is given by:

The object referred to in the question is thrown from a height H=0 and the maximum height is hm=77.5 m.
(a)
To find the initial speed we solve for vo:



(b)
The maximum time or the time taken by the object to reach its highest point is calculated as follows:



<span>D.) The force and displacement are in the same direction.
