Answer:
210 m/s
Explanation:
We will use this equation for an elastic collision:
- m₁v₁ + m₂v₂ = m₁v₁ + m₂v₂
- The left side of the equation is before the collision; the right side is after the collision.
In this case, m₁ = mass of golf ball (0.046 kg) and m₂ = mass of the golf club (0.22 kg).
<h3><u>Left side of equation:</u></h3>
v₁ is 0 m/s since the ball is at rest on the tee.
v₂ is 44 m/s, given in the problem.
<h3><u>Right side of equation:</u></h3>
v₁ is what we are trying to find.
v₂ is 0 m/s since the ball will be at rest on the ground.
<h3>⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯</h3>
Plug these values into the elastic collision equation:
- (0.046 kg)(0 m/s) + (0.22 kg)(44 m/s) = (0.046 kg)(v₁) + (0.22 kg)(0 m/s)
Simplify this equation.
- (0.22 kg)(44 m/s) = (0.046 kg)(v₁)
Get rid of the units.
Multiply the left side of the equation.
Divide both sides by 0.046.
- 210.434782609 = v₁
- 210 m/s = v₁
The speed of the ball when it leaves the tee is about 210 m/s.
do you have a formulai can do this problem
Answer:
714.286 kg
General Formulas and Concepts:
Physics 1
- Fg = mg
Fg is gravitational force in Newtons
m is the mass of the object in kilograms
g is the gravitational acceleration of Earth: 9.8 m/s^2
Step-by-step explanation:
Step 1: Define
7000 N = Fg
g = 9.8 m/s^2
Step 2: Solve for m
1. Substitute: 7000 N = m(9.8 m/s^2)
2. Isolate m: 714.286 kg = m
