Explanation:

What are we to use as gravity in this imaginary world? I will ASSUME 9.81 m/s² and assume no air resistance.

horizontal velocity component

vx = 55.0/2.50 = 22 m/s

vertical initial velocity component

(12.0 - 10.0) = 0 + vy₀(2.50) + ½(-9.81)2.50²

vy₀ = 13.0625 m/s

θ = arctan(vy₀/vx) = arctan(13.0625/22) = 30.6997225... = 30.7°

The figure shows a water-filled syringe with a 4.0-cm-long needle. What is the gauge pressure of the water at the point P, where

mars1129 [50]

Answer:

Pressure at P point is given as

$P_p = 1.042 \times 10^5 Pa$

Explanation:

As we know by poiseuille's equation of viscous flow of liquid through cylindrical pipe

$Q = \frac{\Delta P \pi r^4}{8\eta L}$

here we know that

L = 4 cm

$\eta = 1 \times 10^{-3} Pa s$

r = 1 mm

Q = flow rate

$\pi r^2 v = \frac{\Delta P \pi r^4}{8\eta L}$

$v = \frac{\Delta P r^2}{8 \eta L}$

$10 = \frac{\Delta P (10^{-3})^2}{8(1 \times 10^[-3})(0.04)}$

$3.2 \times 10^{-3} = \Delta P (10^{-6})$

$\Delta P = 3.2 \times 10^3 Pa$

now we have

$P_p - P_{atm} = 3.2 \times 10^3$

$P_p = 1.01 \times 10^5 + 3.2 \times 10^3$

$P_p = 1.042 \times 10^5 Pa$

A truck initially traveling at a speed of 22 m/s increases at a constant rate of 2.4 m/s^2 for 3.2s. What is the total distance

FinnZ [79.3K]

Answer:

82.7 m

Explanation:

u= 22m/s

a= 2.4 m/s^2.

t= 3.2 secs

Therefore the distance travelled can be calculated as follows

S= ut + 1/2at^2

= 22 × 3.2 + 1/2 × 2.4 × 3.2^2

= 70.4 + 1/2×24.58

= 70.4 + 12.29

= 82.7 m

Hence the distance travelled by the truck is 82.7 m
