A water skier has a mass of 86 kg and accelerates at 2 m/s2. What is the net force acting on him?

Physics
1 answer:
Korolek [52]4 years ago
8 0

Answer:

F = 172 N

Explanation:

Newton's second law of motion gives the amount of force acting on an object. Mathematically, it is given by :

F=ma

Put m =86 kg and a = 2 m/s²

So,

F=(86\times 2)\ N\\\\F=172\ N

Hence, the net force is 172 N.

study a 75kg person stands on a scale in an elevator what does read in n and in kg when the elevator is at rest?
Verdich [7]

To solve this problem we will use Newton's second law in order to obtain the weight of a person. The second law tells us that

F = ma

Where,

m = mass

a = Acceleration

In this particular case, the acceleration is equal to that exerted by the earth through gravitational acceleration, so if the person's weight is 75Kg and the gravity is 9.8m / s^2 , the weight of the body will be,

F_W =mg

F_W = (75kg)(9.8m/s^2 )

F_W = 735.75N

When the elevator is at rest this reads 735.75N and 75Kg (The same mass of the person)

Two differences between science activities carried out in a science laboratory and those carried out side of science laboratory.
viva [34]

In a science lab, there is the adequate availability of raw materials for experiments such as chemicals while outside a science lab there isn't.

In a science lab, the availability of apparatuses and sources of heat is higher than outside a science lab.

<h3>What is science laboratory?</h3>

The science lab is a place where the experiments related to the science background are performed with the use of apparatus.

The science lab has plenty of equipment to perform the experiment whether related to physics or chemistry or biology.

Thus, source of heat and availability of raw material and equipment are the differences between the science activities carried out in a science laboratory and those carried out side of science laboratory.

How does changing the voltage in a circuit affect the current in the circuit
Tasya [4]
The formula for the voltage is shown below:
Voltage = Current x Resistance
V=I x R

When we change voltage:
I =V/R or R=V/I
Increasing the voltage in an electrical circuit will also increase the current value, as well as the resistance of the load,

A 1.0 kg cart moving right at 5.0 m/s on a frictionless track collides with a second cart moving at 2.0m/s. The 1.0 kg cart has
____ [38]

Answer:

m₂ = 3kg

Explanation:

The question wasn't clear about what direction the initial velocity of the second cart was, so I'll assume it was going left at 2.0m/s.

Anyway, this is a conservation of momentum problem. The equation you need to use is the one written in blue. They want you to solve for the mass of the second cart, so do some algebra and rearrange that blue equation in term of m₂.

Now that you have the equation for m₂, plug in all the values given from the question and you'll get 3kg.
