Answer:

1.76m/s²

Explanation:

Given parameters:

Initial velocity  = 0m/s

Final velocity  = 65m/s

Distance traveled  = 1200m

Unknown:

Acceleration  = ?

Solution:

This is linear velocity and we apply the appropriate motion equation to solve this problem.

      V²  = U² + 2as

S is the distance

u is the initial velocity

V is the final velocity

a is the acceleration

Now, insert the parameters and solve;

             65²  =  0² + 2 x a x 1200

             4225 = 2400a

                  a  = 1.76m/s²

A 75.0 kg diver falls from rest into a swimming pool from a height of 5.10 m. It takes 1.34 s for the diver to stop after enteri
vichka [17]

Answer:

559.5 N

Explanation:

Applying,

v² = u²+2gs............. Equation 1

Where v = final velocity,

From the question,

Given: s = 5.10 m, u = 0 m/s ( from rest)

Constant: 9.8 m/s²

Therefore,

v² = 0²+2×9.8×5.1

v² = 99.96

v = √(99.96)

v = 9.99 m/s

As the diver eneters the water,

u = 9.99 m/s, v = 0 m/s

Given: t = 1.34 s

Apply

a = (v-u)/t

a = 9.99/1.34

a = -7.46 m/s²

F = ma.............. Equation 2

Where F = force, m = mass

Given: m = 75 kg, a = -7.46 m/s²,

F = 75(-7.46)

F = -559.5 N

Hence the average force exerted on the diver is 559.5 N

A car tire contains 0.0380m3 of air at a pressure of 2.20×105N/m2 (about 32 psi). How much more internal energy does this gas ha
emmasim [6.3K]

Answer:

\Delta U = 11305 J

Explanation:

As per ideal gas equation we know that

PV = nRT

here we know that

P = 2.20 \times 10^5 Pa

V = 0.0380 m^3

now we have

nRT_1 = (2.20 \times 10^5)(0.0380) = 8360 J

now for other case at zero gauge pressure we have

P = 1.01 \times 10^5 Pa

V = 0.0380 m^3

we have now

nRT_2 = (1.01 \times 10^5)(0.0380) = 3838 J

now the difference in internal energy of air is given as

\Delta U = \frac{5}{2}nR\Delta T

\Delta U = \frac{5}{2}(8360 - 3838)

\Delta U = 11305 J
