Answer:

force normal = mass times acceleration

F=ma

54= m (3.8)

divide by 3.8 in both sides

54/3.8

mass of the little brother is 14.2 kg

It doesn't mean that the climate is changing, it is probably just the morning dew.

Calculate the east component of a resultant 32.5 m/s, 35.0° east of north.

ValentinkaMS [17]

Answer:

East component is: 18.64 m/s

Explanation:

If the resultant is 32.5 m/s directed 35 degrees east of north, then we use the sin(35) projection to find the east component of the velocity:

East component = 32.5 m/s * sin(35) = 18.64 m/s

How much work is required to move

Nikitich [7]

The work is path independent since we have a conservative force.

Thus $W=d\cdot\frac{q\cdot U}{d^2}=\frac{3.0\cdot9.0}{0.010}=\boxed{2700 J}$
