Kasi ya mstari - matatizo na suluhisho

1. An object travels at a constant 10 m/s. Calculate the linear momentum ya kitu hicho.

Inajulikana :

Misa (m) = kilo 1

Kasi (v) = 10 m/s

Inayohitajika: linear momentum (p)

Suluhisho:

Formula of the linear momentum :

p = mv

p = linear momentum, m = mass, v = velocity

The linear momentum :

p = m v = (1)(10) = 10 kg m/s²

2. A 2-kg block and a 4-kg blocks moves at a constant 20 m/s. What is the linear momentum of the blocks.

Inajulikana:

Misa ya block A (m_A) = kilo 2

Misa ya block B (m_B) = kilo 4

Velocity of block A (v_A) = 20 m/s

Velocity of block B (v_B) = 20 m/s

Inayohitajika: Linear momentum of block A (p_A) and linear momentum of block B (p_B)

Suluhisho:

Linear momentum of block A :

p_A = m_A v_A = (2)(20) = 40 kg m/s

Linear momentum of block B :

p_B = m_B v_B = (4)(20) = 80 kg m/s

3. A 2-kg block moves at a constant 2 m/s and a 2-kg block moves at a constant 4 m/s. Determine the linear momentum of the blocks.

Inajulikana:

Misa ya block A (m_A) = kilo 2

Mass of block B (m_B) = kilo 2

Velocity of block A (v_A) = 2 m/s

Velocity of block B (v_B) = 4 m/s

Inayohitajika: the linear momentum of blocks

Suluhisho:

Linear momentum of block A :

p_A = m_A v_A = (2)(2) = 4 kg m/s

Linear momentum of block B :

p_B = m_B v_B = (2)(4) = 8 kg m/s

4. A 5-kg object at rest. What is the linear momentum of the momentum.

Inajulikana:

Uzito (m) = kilo 5

Object’s velocity (v) = 0

Alitaka : the linear momentum (p)

Suluhisho:

p = m v = (5)(0) = 0
