A 92-kg fullback moving south with a speed of 5.8 m/s is tackled by a 110-kg lineman running west with a speed of 3.6 m/s. Assum
MariettaO [177]

Answer:

The speed and direction of the two players immediately after the tackle are 3.3 m/s and 53.4° South of West

Explanation:

given information:

mass of fullback, m_{x} = 92 kg

speed of full back, v_{x} = 5.8 to south

mass of lineman, m_{y} =110 kg

speed of lineman, v_{y} = 3.6

according to conservation energy,

assume that the collision is perfectly inelastic, thus

initial momentum = final momentum

                            P_{ix} = P_{x}'

                          m₁v₁ = (m₁+m₂)v_{x}'

                             v_{x}' = m₁v₁/(m₁+m₂)

                                  = (92) (5.8)/(92+110)

                                  = 2.64 m/s

                            P_{iy} = P_{y}'

                         m₂v₂ = (m₁+m₂)v_{y}'

                             v_{y}' = m₁v₁/(m₁+m₂)

                                  = (110) (3.6)/(92+110)

                                  = 1.96 m/s

thus,

v' = √v_{x}'²+v_{y}'²

  = 3.3 m/s

then, the direction of the two players is

θ = 90 - tan⁻¹(v_{y}'/v_{x}')

  = 90 - tan⁻¹(1.96/2.64)

  = 53.4° South of West

What is the acceleration along the ground of a 10 kg wagon when it is pulled with a force of 44 N at an angle of 35° above the
Olegator [25]

The acceleration of the wagon along the ground is 3.6 m/s².

To solve the problem above, we need to use the formula of acceleration as related to force and mass.

Acceleration: This can be defined as the rate of change of velocity.

⇒ Formula:

  • Fcos∅ = ma................. Equation 1

⇒ Where:

  • F = Force
  • ∅ = angle above the horizontal
  • m = mass of the wagon
  • a = acceleration of the wagon

⇒ make a the subject of equation 1

  • a = Fcos∅/m..................... Equation 2

From the question,

⇒ Given:

  • F = 44 N
  • ∅ = 35°
  • m = 10 kg

⇒ Substitute these values into equation 2

  • a = 44(cos35°)/10
  • a = 44(0.8191)/10
  • a = 3.6 m/s²

Hence, The acceleration of the wagon along the ground is 3.6 m/s²
