Answer: (displacement/delta x) = -50. m, and distance dropped = 50. m (50. m below the starting location)

Explanation:

We know that the initial velocity of the tuna can is 0 m/s, as it is at rest. Also, we have the acceleration caused by gravity (-9.8 m/s^2). The time for the trip is 3.2 s. We need to find the displacement, or delta x.

To do this, we need to use a freefall equation. The one we can use with initial velocity, time, and acceleration would be the following:

d = (initial velocity)(time) + (1/2)(acceleration caused by gravity)(time)^2

d = (vi)(t) + 1/2(g)(t)^2

d = (0 m/s)(3.2 s) + 1/2(-9.8 m/s^2)(3.2 s)^2

d = 1/2(-9.8 m/s^2)(3.2 s)^2

d = -4.9(3.2)^2

d = -4.9(10.24)

d = -50.176 = <u><em>-50. m</em></u>

You drop a 14-g ball from a height of 1.5 m and it only bounces back to a height of 0.85 m. what was the total impulse on the ba
Allisa [31]
<span>Remember that  impulse = change in momentum 

this means we compute the momentum of the ball just before impression and just after; we know the mass, so we find the speeds 

the ball falls for 1.5m and will achieve a speed given by energy conservation: 

1/2 mv^2 = mgh => v=sqrt[2gh]=5.42m/s 

since it rises only to 0.85 m, we compute the initial speed after power from the same equation and get 
v(after)=sqrt[2*9.81m/s/s*0.85m] = 4.0837 m... 

now, recall that momentum is a vector, so that the momentum down has one sign and the momentum up has a positive sign, so we have 

impulse = delta (mv) = m delta v = 0.014 kx (4.08m/s - (-5.42m/s) = 0.133 kgm/s </span>

Sam is pulling a box up to the second story of his apartment via a string. The box weighs 16.5 kg and starts from rest on the gr
Katyanochek1 [597]

Answer:

Weight (mass) = 16.5 kg

velocity = 0 m/a

acceleration =2.6 m/s^2

displacement = 13.2m

now,

acceleration = velocity/ time

2.6 = 0 / t

t = o / 2.6

t = o

At constant volume, the heat of combustion of a particular compound is − 3550.0 kJ / mol. When 1.075 g of this compound ( molar
swat32

Answer:

C=1,25\cdot 10^{5} kJ/^{\circ}C

Explanation:

First of all let's define the specific molar heat capacity.

C = \frac{-Q}{n\cdot \Delta T} (1)

Where:

Q is the released heat by the system

n is the number of moles

ΔT is the difference of temperature of the system  

Now, we can find n with the molar mass (M) the mass of the compound (m).

n=\frac{m}{M}=6.95\cdot 10^{-3} moles      

Using (1) we have:

C=\frac{-3550}{6.95\cdot 10^{-3} 4.073}

C=1,25\cdot 10^{5} kJ/^{\circ}C

I hope it helps!
