in 1994, Vladimir Kurlivich , from Belarus, set the world record as the world's strongest weight lifter. he did this by lifting and holding above his head a barbell whise mass was 253kg. Kurlovich's mass at the time was 133 kg. caculate the normal force exerted on each of his feet during the time he. was having ldi g the barbell

Answers

The free-body diagram of your question is; 2 downward forces (253 kg mass of barbell & 133 kg body mass of Kurlovich) acting together on a point supported by 2 upward forces as normal forces exerted by Kurlovich's feet.

Solving the normal forces exerted by 2 feet :

Summation of Forces Vertical = 0

2 Dowwnard Forces = 2 Upward Forces (2F)

253 + 133 = 2F

2F = 386 Kgs

F = 386 / 2

F = 193 Kgs (Normal Force Exerted by Each Foot)

Final answer:

To calculate the normal force exerted on each of Vladimir Kurlovich's feet while lifting the barbell, we need to consider the weights of Kurlovich and the barbell. The normal force is equal to the sum of the two weights.

Explanation:

To calculate the normal force exerted on each of Vladimir Kurlovich's feet while lifting the barbell, we need to consider the weight of Kurlovich and the weight of the barbell. The normal force is equal to the sum of Kurlovich's weight and the weight of the barbell, as it balances the gravitational force pulling them downwards. Kurlovich's weight can be calculated using his mass and the acceleration due to gravity, which is approximately 9.8 m/s².

Step 1:

Calculate Kurlovich's weight:
Mass = 133 kg
Acceleration due to gravity = 9.8 m/s²
Weight = Mass × Acceleration due to gravity
Weight = 133 kg × 9.8 m/s²

Step 2:

Calculate the weight of the barbell:
Mass = 253 kg
Acceleration due to gravity = 9.8 m/s²
Weight = Mass × Acceleration due to gravity
Weight = 253 kg × 9.8 m/s²

Step 3:

Calculate the normal force exerted on each foot:
Normal force = Kurlovich's weight + Barbell's weight

Two billiard balls move toward each other on a table. The mass of the number three ball, m1, is 5 g with a velocity of 3 m/s. The mass of the eight ball, m2, is 6 g with a velocity of 1 m/s. After the balls collide, they bounce off each other. The number three ball moves off with a velocity of 5 m/s. What is the final velocity and direction of the eight ball? +8.6 m/s +5.7 m/s –5.7 m/s –8.6 m/s.?

Answers

Answer:

+5.7 m/s

Explanation:

According to the law of conservation of momentum is that the momentum before the collision is equal to the momentum after the collision. In an equation form it would look like this:

M₁V₁+M₂V₂ = M₁V₁'+M₂V₂'

Where:

M₁ = mass of object 1 (kg)

V₁ = velocity of object 1 before the collision (m/s)

V₁' = Final velocity of object 1 after the collision (m/s)

M₂ = mass of object 2 (kg)

V₂ = velocity of object 2 before the collision (m/s)

V₂' = Final velocity of object 2 after the collision (m/s)

According to your problem you have the following given:

M₁ = 5 g = 0.005kg

V₁ = 3 m/s

V₁' = -5m/s (It bounced off so it is going the other direction)

M₂ = 6g = 0.006kg

V₂ = -1 m/s (It is coming from the opposite direction of the 3-ball)

V₂' = ?

So we plug in what we know and solve for what we don't know.

$M_1V_1+M_2V_2 = M_1V_1' + M_2V_2'\n\n(0.005kg)(3m/s)+(0.006kg)(-1m/s) = (0.005kg)(5m/s)+(0.006kg)(V_2')\n\n(0.015kg\cdot m/s)+(-0.006kg\cdot m/s)=(-0.025kg\cdot m/s)+(0.006kg)(V_2')\n\n0.009kg\cdot m/s+0.025kg\cdot m/s = (0.006kg)(V_2')\n\n(0.034kg\cdot m/s)/(0.006kg) = V_2'\n\n5.7m/s = V_2'$

Answer:

+5.7 m/s

Just did the assignment :)

two objects were lifted by a machine. one object had a mass of 2 kilograms and was lifted at the speed of 2 m/s. the other had a mass of 4 kilograms and was lifted at a rate of 3 m/s. which object had more kinetic energy while it was being lifted?"

Answers

to find the kinetic energy KE=1/2 × mass × velocity ^2
for object 1 ke= 1/2(2)(2^2)=4 J
for object 2 ke= 1/2(4)(3^2)=18J
meaning object 2 as more kinetic energy
