A rugby player sits on a scrum machine that weighs 200 Newtons. Given that the coefficient of static friction is 0.67, the coeff

Trava [24]

a. 850 N is the minimum force needed to get the machine/player system moving, which means this is the maximum magnitude of static friction between the system and the surface they stand on.

By Newton's second law, at the moment right before the system starts to move,

• net horizontal force

∑ F[h] = F[push] - F[s. friction] = 0

• net vertical force

∑ F[v] = F[normal] - F[weight] = 0

and we have

F[s. friction] = µ[s] F[normal]

It follows that

F[weight] = F[normal] = (850 N) / (0.67) = 1268.66 N

where F[weight] is the combined weight of the player and machine. We're given the machine's weight is 200 N, so the player weighs 1068.66 N and hence has a mass of

(1068.66 N) / g ≈ 110 kg

b. To keep the system moving at a constant speed, the second-law equations from part (a) change only slightly to

∑ F[h] = F[push] - F[k. friction] = 0

∑ F[v] = F[normal] - F[weight] = 0

so that

F[k. friction] = µ[k] F[normal] = 0.56 (1268.66 N) = 710.45 N

and so the minimum force needed to keep the system moving is

F[push] = 710.45 N ≈ 710 N

Metal sphere having an excess of +5 elementary charges has a net electric charge of

Natasha2012 [34]

Answer:

$q=+8.01\cdot 10^{-19}\ coulombs$

Explanation:

<u>Elementary charge</u>

The elementary charge, denoted by the symbol e is the electric charge carried by a proton or, equivalently, the magnitude of a negative electric charge carried by an electron, which has charge −e.

The value of the elementary charge is a fundamental constant in physics:

$\mathbf{e}=1.60217662 \cdot 10^{-19}\ coulombs$

If a metal sphere has an excess of +5 elementary charge, then it has a net charge of:

$q=5*\mathbf{e}=+5*1.60217662 \cdot 10^{-19}\ coulombs$

$\boxed{q=+8.01\cdot 10^{-19}\ coulombs}$

40 miles/hour

Details:
after one hour they have traveled 40mi. So they have traveled 40mi. in 1hr, or 40mi/1hr or 40mi/hr.

the problem is about reading a graph. the graph says that they traveled 40 miles in the first hour

formula for average speed:
miles traveled/time it took=speed or d/t=r
