The position of the object at time t =2.0 s is <u>6.4 m.</u>
Velocity vₓ of a body is the rate at which the position x of the object changes with time.
Therefore,

Write an equation for x.

Substitute the equation for vₓ =2t² in the integral.

Here, the constant of integration is C and it is determined by applying initial conditions.
When t =0, x = 1. 1m

Substitute 2.0s for t.

The position of the particle at t =2.0 s is <u>6.4m</u>
B: CaO
Because Calcium is a Metal and Oxygen is a Non-Metal. Ionic bonds are only formed with a Metal and a Non-Metal element.
Answer:
B. Researching the problem, using information from a variety of sources
Explanation:
First you must create a hypothesis because with out a hypothesis you can’t do the experiment. Then you have to do some research on your problem/ hypothesis from reliable sources. After have your research you can organize your data with a data table or chart. Then when have your research look for the independent and dependent variable and the control. Then you have to make a conclusion based on multiple experimental trials then repeat the experiment and if it ends up different from the first then something is wrong and that means that you did something wrong. Hopefully this helps you :)
pls mark brainlest ;)
#1
Work done is given by

here we know that
F = 157 N
d = 14.5

now from the above formula

#2
By energy conservation
Initial total potential energy of egg = final total kinetic energy of egg




#3
By momentum conservation we know that




#4
by momentum conservation we know that

let direction of velocity of Jay Z car motion is positive direction
now we will say



Yes Jay Z is overspeeding as his speed is more than speed limit
#5
Tension force in the string will be centripetal force
so here we can say

here we know that
m = 0.63 kg
v = 7.8 m/s
R = 0.23 m
