Hello.
I am trying to calculate the ground reaction forces of a horse walking as I have got the reaction force of them standing in one spot. The weight of the horse is 500kg and distributed 52% of weight on the front legs. The answer for both front legs was 2548N and one leg being half of this. I am wondering how to get the forces of the horse was walking on a hard surface such as concrete
thanks
The plunger and the needle of a hypodermic syringe have areas of 0.5 cm2 and 0.0006 cm2 , respectively. To inject a vaccine, a nurse pushes the plunger with a force of 5.5 N. What pressure is transmitted to the vaccine?

A piece of iron placed on a block of wood makes it float lower in the water, If the iron were instead suspended beneath the wood, would it float as low, lower, or higher? Defend your answer.
Β 1.A truck and an ambulance move at the same rate of 13 m/s toward each other but on different lanes. If the ambulance siren emits sound of frequency 1200 Hz, what is the frequency of the sound that the truck driver hears?
2. The police car is moving toward a warehouse at 30 m/s.Β If the police car is emitting a 1kHz sound, what frequency does the driver hear reflected from the warehouse? Assume that the speed of sound is 340 m/s.
3. What is the frequency heard by a person driving at 15 m/s toward a factory whistle that is blowing at a frequency of 800 Hz? Assume that the speed of sound is 340 m/s
1. A police carβs siren emits a sinusoidal wave with frequency of 300 Hz. The speed of sound is 340 m/s and the air is still.
a.) If a listener is at rest and the siren is moving away at 30 m/s, what frequency does the listener hear?
b.) If the siren is at rest and the listener is moving away from it at 30 m/s, what frequency does the listener hear?
2. The siren is moving away from the listener with a speed of 45 m/s relative to the air, and the listener is moving toward the siren with a speed of 15 m/s relative to the air. If the siren is emitting a 1kHz sound, what frequency does the listener hear?

On a very hot day in Manila, an oil tanker loaded 50,000 liters of fuel. It traveled to Baguio, which was 20 K colder than Manila. How many liters where delivered to Baguio? (π½πππ πππππ=0.95 π₯ 10β3)
Using the equation for acceleration due to gravity (g), compute the
approximate value of acceleration due to gravity with the given values: mass of Earth = 6.0 x 10^24kg and radius of Earth = 6.37 x 10^6 m. Compare the value you had with the
acceleration due to gravity we use which is 9.8 m/s^2
