Answer:

68.8 N

Explanation:

From the question given above, the following data were obtained:

Mass (m) of box = 18 Kg

Coefficient of friction (μ) = 0.39

Force of friction (F) =?

Next, we shall determine the normal force of the box. This is illustrated below:

Mass (m) of object = 18 Kg

Acceleration due to gravity (g) = 9.8 m/s²

Normal force (N) =?

N = mg

N = 18 × 9.8

N = 176.4 N

Finally, we shall determine the force of friction experienced by the object. This is illustrated below:

Coefficient of friction (μ) = 0.39

Normal force (N) = 176.4 N

Force of friction (F) =?

F = μN

F = 0.39 × 176.4

F = 68.796 ≈ 68.8 N

Thus, the box experience a frictional force of 68.8 N.

A mass m1= 6.20 kg is moving North with a velocity of v1= 13.5m/sec when it collides perpendicularly with another mass m2= 4.40
JulijaS [17]

Answer:

Momentum of mass m_{1} is 83·7 kg m/s towards north

Momentum of mass m_{2} is 38·72 kg m/s towards east

Explanation:

Given

Mass of m_{1} = 6·2 kg

Mass of m_{2} = 4·4 kg

Velocity of mass m_{1} = v_{1} = 13·5 m/s

Velocity of mass m_{2} = v_{2} = 8·8 m/s

Momentum of mass m_{1} = m_{1} × v_{1} = 6·2 × 13·5 = 83·7 kg m/s

Momentum of mass m_{2} = m_{2} × v_{2} = 4·4 × 8·8 = 38·72 kg m/s

As mass m_{1} is moving North, the direction of momentum will also be in that direction because the direction of momentum will be in the direction of velocity

As mass m_{2} is moving East, the direction of momentum will also be in that direction because the direction of momentum will be in the direction of velocity

∴ Momentum of mass m_{1} is 83·7 kg m/s towards north

∴ Momentum of mass m_{2} is 38·72 kg m/s towards east
