Answer:
Explanation:
It's equal to change of momentum in contact
X-rays have the shortest wavelength of any waves on that particular list.
Gamma ray waves are shorter than X-rays, but they're not on that list.
Answer:
t = 0.5 seconds
Explanation:
Given that,
Mass of a body, m = 50 kg
Initial speed, u = 0
Final speed, v = 5 m/s
The resistance force of the ground = 500 N
We need to find the time of contact. The formula for the force acting on an object is given by :
F = ma
a is acceleration
So, the time of contact is 0.5 seconds.
