Drawing a shows a displacement vector (450.0 m along the y axis). In this x, y coordinate system the scalar components are Ax 0

Alisiya [41]

Answer:

x ’= 368.61 m, y ’= 258.11 m

Explanation:

To solve this problem we must find the projections of the point on the new vectors of the rotated system θ = 35º

x’= R cos 35

y’= R sin 35

The modulus vector can be found using the Pythagorean theorem

R² = x² + y²

R = 450 m

we calculate

x ’= 450 cos 35

x ’= 368.61 m

y ’= 450 sin 35

y ’= 258.11 m

A heavy ball with a weight of 150 N is hung from the ceiling of a lecture hall on a 4.1-m-long rope. The ball is pulled to one s

AlladinOne [14]

Answer:

The tension in the rope is 262.88 N

Explanation:

Given:

Weight $W = 150$ N

Length of rope $r = 4.1$ m

Initial speed of ball $v = 5.5 \frac{m}{s}$

For finding the tension in the rope,

First find the mass of rod,

$mg = 150$ ( $g = 9.8 \frac{m}{s^{2} }$ )

$m = \frac{150}{9.8}$

$m = 15.3$ kg

Tension in the rope is,

$T = mg + \frac{mv^{2} }{r}$

$T = 150 + \frac{15.3 \times (5.5)^{2} }{4.1}$

$T = 262.88$ N

Therefore, the tension in the rope is 262.88 N

Ice has a density of 0.920 g/cm3. An ice cubes mass is 100 g. What is its volume?

Tasya [4]

Answer:

$\boxed {\tt 108.695652 \ cm^3}$

Explanation:

Volume can be found by dividing the mass by the density.

$v=\frac{m}{d}$

The mass is 100 grams and density is 0.920 grams per cubic centimeters.

Therefore,

$m=100 \ g \\d= 0.920 \ g/cm^3$

Substitute the values into the formula.

$v=\frac{100 \ g}{0.920 \ g/cm^3}$

Divide. Note that the grams, or "g" will cancel each other out.

$v- 108.695652 \ cm^3$

The volume of the ice cube is 108.697652 cubic centimeters.
