A 100-g toy car moves along a curved frictionless track. At first, the car runs along a flat horizontal segment with an initial

Sholpan [36]

Answer:

2.994 m/s

Explanation:

m = Mass of the car = 100 g

$v_1$ = Initial velocity = 3.33 m/s

h = Height = 0.108 m

g = Acceleration due to gravity = 9.81 m/s²

We know that energy in the system is conserved so

$\dfrac{1}{2}mv_1^2=mgh+\dfrac{1}{2}mv_f^2\\\Rightarrow v_f=\sqrt{2\left({\dfrac{1}{2}v_1^2-gh}\right)}\\\Rightarrow v_f=\sqrt{2\left(\dfrac{1}{2}3.33^2-9.81\times 0.108\right)}\\\Rightarrow v_f=2.994\ m/s$

The final velocity of the car is 2.994 m/s

A 70.0-kg person throws a 0.0420-kg snowball forward with a ground speed of 35.0 m/s. A second person, with a mass of 57.0 kg, c

ollegr [7]

Answer:

so throwers new velocity = 2.18032m/s

so catchers new velocity = 0.02577m/s

Explanation:

Directly by conservation of momentum we can write

$m_1u_1+m_2u_2= m_1v_1+m_2v_2$

let x be the thrower's new velocity

(70+0.042)×2.2 + 57×0 = 70× x +0.042×35 +57×0

x = 2.18032m/s

so the velocity of 70 kg man = 2.18032m/s

so throwers new velocity = 2.18032m/s

now again by conservation of momentum

0.042×35 = (57+0.042) ×y

y = 0.02577m/s

so catchers new velocity = 0.02577m/s

An RLC series circuit has an applied voltage of 240 volts. R = 48 Ω, XL = 100 Ω, XC = 36 Ω, and Z = 80 Ω. What is the voltage dr

mestny [16]

Answer:

I44volts

Explanation:

Given that,

Vc= IXc

I = V/Z

Where V = 240 volts, Z= 80 ohms

Hence, I = V/Z = 240÷80

I = 4A

Xc=36 ohms

Vc = IXc = 4×36

Vc = 144volts
