Answer:

KE = 5.01 \times 10^{-13}Joules

Explanation:

Kinetic energy is the energy possessed by a body by virtue of its motion. It is expressed as;

KE = \frac{1}{2}mv^2\\ where:

m is the mass of proton

v is the speed

Substitute:

KE = \frac{1}{2}(1.67\times 10 ^{-27})(6.0\times10^7)^2\\\\KE = \frac{1}{2}(1.67\times 10 ^{-27})(6.0\times10^{14})\\\\\\KE = \frac{1}{2}(1.67\times 6.0 \times 10 ^{-27}\times10^{14})\\\\KE =  \frac{1}{2}(1.67\times 6.0 \times 10 ^{-27+14})\\\\KE = 3 \times 1.67 \times 10^{-13}\\\\KE = 5.01 \times 10^{-13}Joules

Hence the kinetic energy of a proton is 5.01 \times 10^{-13}Joules

A rod 7.0 m long is pivoted at a point 2.0 m from the left end. A downward force of 50 N acts at the left end, and a downward fo
kicyunya [14]

If the rod is in rotational equilibrium, then the net torques acting on it is zero:

∑ τ = 0

Let's give the system a counterclockwise orientation, so that forces that would cause the rod to rotate counterclockwise act in the positive direction. Compute the magnitudes of each torque:

• at the left end,

τ = + (50 N) (2.0 m) = 100 N•m

• at the right end,

τ = - (200 N) (5.0 m) = - 1000 N•m

• at a point a distance d to the right of the pivot point,

τ = + (300 N) d

Then

∑ τ = 100 N•m - 1000 N•m + (300 N) d = 0

⇒   (300 N) d = 1100 N•m

⇒   d ≈ 3.7 m

An 800 N man climbs 5 m up a ladder. How much gravitational potential energy does he gain?
Artemon [7]

Answer:

4000J

Explanation:

Given parameters:

Weight of the man  = 800N

Height of ladder  = 5m

Unknown:

Gravitational potential energy gained  = ?

Solution:

The gravitational potential energy is due to the position of a body.

 Gravitational potential energy = weight x height

Now insert the parameters;

 Gravitational potential energy  = 800 x 5  = 4000J

Sheila weighs 60 kg and is riding a bike. Her momentum on the bike is 340 kg • m/s. The bike hits a rock, which stops it complet
Vikki [24]

Answer:

v₂ = 5.7 m/s

Explanation:

We will apply the law of conservation of momentum here:

Total\ Initial\ Momentum = m_{1}v_{1} + m_{2}v_{2}\\

where,

Total Initial Momentum = 340 kg.m/s

m₁ = mass of bike

v₁ = final speed of bike = 0 m/s

m₂ = mass of Sheila = 60 kg

v₂ = final speed of Sheila = ?

Therefore,

340\ kg.m/s = m_{1}(0\ m/s) + (60\ kg)v_{2}\\v_{2} = \frac{340\ kg.m/s}{60\ kg}\\\\

<u>v₂ = 5.7 m/s </u>
