<u>Answer:</u> The ball is travelling with a speed of 5.5 m/s after hitting the <u>bottle.</u>
<u>Explanation:</u>
To calculate the speed of ball after the collision, we use the equation of law of conservation of momentum, which is given by:
where,
are the mass, initial velocity and final velocity of ball.
are the mass, initial velocity and final velocity of bottle.
We are given:
Putting values in above equation, we get:
Hence, the ball is travelling with a speed of 5.5 m/s after hitting the bottle.
Explanation:
μ = coefficient of friction.
F = Frictional force = 12N
R = Normal reaction = mg = Weight = 240N
m = mass
g = acceleration due to gravity ≈ 9.8ms—²
μ = F/R
<em>μ </em><em>=</em><em> </em><em>1</em><em>2</em><em>/</em><em>2</em><em>4</em><em>0</em>
<em>μ </em><em>=</em><em> </em>¹/20
μ = 0.05
<span>It takes only one atom to make hydrogen; however, hydrogen is commonly found as H2, meaning two atoms make up hydrogen. Because of this, hydrogen is known as a diatomic element
The answer is prob A.1 but you didnt' give me a formula.</span>
Answer:
Bowling Ball
Explanation:
The potential energy depends on the factors: mass of the object and distance between the two objects. In this case the distance is between the ground and the balls. Here, the bowling ball is heaviest and its center of mass is farthest in comparison to other two balls. Thus, it has the greatest potential energy.
