Answer:
A) c₁ = m, c₂ = m/s
B) c₁ = m/s²
C) c₁ = m/s²
D) c₁ = m/s c₂ = °
E) c₁ = m/s , c₂ = /s
Explanation:
A) x = c₁ + c₂t
⇒m = m + (m/s)s (Only same units can be added)
⇒m = m
So, c₁ = m, c₂ = m/s
B) x = 0.5c₁t²
⇒m = 0.5 (m/s²)s²
⇒m = m
So, c₁ = m/s²
C) v² = 2c₁x
⇒m²/s² = 2 (m/s²)m
⇒m²/s² = m²/s²
So, c₁ = m/s²
D) x = c₁ cos(c₂)t
⇒m = (m/s) cos(°)s
⇒m = m
So, c₁ = m/s c₂ = °
E) v² = 2c₁v-(c₂x)²
⇒m²/s² = 2(m/s)(m/s)-(1/s²)(m²)
⇒m²/s² =m²/s²
So, c₁ = m/s , c₂ = /s
Answer:
Ball A will move towards West with speed 8 m/s
Ball B will move towards East with speed 12 m/s
Explanation:
As we know that during collision there is no external force on the system
So here we can use momentum conservation for finding the final velocities of two balls
so we have
since two balls are identical so we have
also we know that for elastic collision we have
so we have
so we have
Towards East
Towards West
Answer:
The potential energy has a maximum when the ball is a time that is half of the time for total travel
Explanation:
Generally potential energy is a the varies directly with the height according to this formula
and the ball attains a maximum height when the time is equal to half of the total time taken to travel
If you don't wear a helmet and let's say you fell off your bike, you can severely injure your head! But if you DO wear a helmet and you fell off your bike, there's about I predict a 98% chance that you won't injure but sometimes it's 100%
hope this helps!<span />
