<h2>Answer</h2>
1m/s
<h2>Explanation</h2>
Given that:
<em>Mass of first blob = 2kg = m1</em>
<em>Velocity of blob = 4m/s = v1</em>
<em>Mass of second blob = 6kg = m2</em>
<em>Velocity of blob = 0m/s = v2</em>
<em />
To find:
<em>Final velocity = Vf</em>
<em />
<em>This question is of inelastic collision which is any collision between objects in which some energy is lost.</em>
<em />
<h3>Formula to be use:</h3><h2>(m1*v1) + (m2*V2) = Vf(m1 + m2)</h2>
(2*4) + (6*0) = Vf(2+6)
8 + 0 = Vf(8)
8 = Vf(8)
Vf = 1 m/s
So the speed of two blobs immediately after colliding = 1 m/s
"Minimum" means a solid barrier under you, so you can't go
through it to any place that's lower. There are several of those
in your house.
Each one is called a ' floor '.
Answer:
a = 6.7 m/s²
Explanation:
The formula to apply here is :
Mass * acceleration = Tension -weight
m*a = Ft -mg -----where m is mass of block, a is acceleration , Ft is force due to tension.
Given in the question that ;
Mass of block = 3 kg
Ft = 50 N
g= 10
m*a = Ft -mg
3*a = 50-30
3a= 20
a= 20/3
a= 6.7 m/s²
Answer:
Height of the racket ball = 0.86 m
Explanation:
Given:
Speed of the tennis ball,
= 31 m/s
Distance covered, 
= 13.3 m
We have to find the height of the racket ball when it left the racket.
Lets say that the time taken by the ball to hit the court be 't' seconds.
⇒ 
⇒ 
⇒ 
⇒ 
seconds
Now we have to find the height lets say that the height is 'h' meter.
⇒ 
...<em>second equation of motion</em>
⇒ 
<em>...initial velocity = 0 and acceleration = gravity </em>
⇒ 
⇒ 
⇒ 
meter.
So the height of the racket ball when it left the racket is of 0.86 m.
