During the time that the blocks are in contact, describe whether the center of mass of the two-block system is speeding up, slow
iVinArrow [24]

Answer:

The center of mass of the two-block system is staying the same and it can be explained with the help of linear momentum equation.

Explanation:

The center of mass of the two-block system is staying the same and it can be explained with the help of linear momentum equation.

Equation:

P=mv

This equation holds if no external force is acting on the system it means the momentum of the system is constant.

In our case, there is no external force which means the total momentum of system is constant:

P=constant

Total mass of system is also constant:

m=constant

It means the velocity of the system is constant (from above equation) thus center of mass of the two-block system is staying the same

Can two vectors of an unequal magnitude add up to give a vector with a magnitude of zero?
Mademuasel [1]
Two vectors of unequal magnitude can never sum to zero. If they point along the same line, since their magnitudes are different, the sum will not be zero.

A 0.80 kg basketball traveling upward at 5.0 m/s impacts an 8.0 10 kg tennis ball traveling downward at 5.0 m/s. The basketball’
vlabodo [156]

To solve this problem we will apply the concepts related to the conservation of momentum. This can be defined as the product between the mass and the velocity of each object, and by conservation it will be understood that the amount of the initial momentum is equal to the amount of the final momentum. By the law of conservation of momentum,

m_1u_1+m_2u_2 = m_1v_1+m_2v_2

Here,

m_1 = Mass of Basketball

m_2 = Mass of Tennis ball

u_1 = Initial velocity of Basketball

u_2 = Initial Velocity of Tennis ball

v_1 = Final velocity of Basketball

v_2 = Final velocity of the tennis ball

Replacing,

(0.8)(0.5)+(0.1)(-5.0)=(0.8)(0.3)+(0.1)v_2

Solving for the final velocity of the tennis ball

v_2 = 11m/s^2

Therefore the velocity of the tennis ball after collision is 11 m/s
