Answer:

Vx = 35 x cos(13deg)

Vy = 35 x sin(13deg) - gt  

(g is acceleration due to gravity =~9.8 meter/second^2, t is time in second)

Explanation:

The tiger leaps up, then x and y component of its velocity are:

Vx = Vo x cos(alpha)

Vy = Vo x sin(alpha) - gt

(Vo is tiger's initial velocity, alpha is angle between its leaping direction and horizontal plane)

Hope this helps!

Plot vector R 50m at an angle of 28 degrees wrtto the positive x axis. Find the x and y components of the vector and write it in
atroni [7]

The x and y-components of the vector R is 44.15i + 23.47j.

The given parameters:

  • Magnitude of vector R = 50 m
  • Position of vector R = 28 degrees

<h3>What is component vectors?</h3>
  • This is the representation of vectors in x and y-coordinates.

The x and y-components of the vector R is calculated as follows;

R_x = R \times cos(\theta)\\\\R_y = R \times sin(\theta)\\\\R_x = 50 \times cos(28) = 44.15 \ i\\\\R_y = 50 \times sin(28) = 23.47 \ j

R is a unit vector.

The plot of vector R is in the image uploaded.

which of the following values can you find by calculating the slope of a graph of velocity versus time position . displacement .
statuscvo [17]
The correct answer is: acceleration.

In fact, the slope of the graph of velocity versus time corresponds to the ratio between the variation of v and the variation of t:
\frac{\Delta v}{\Delta t}
But this is exactly the definition of acceleration: a= \frac{\Delta v}{\Delta t}, so acceleration is the correct answer.

device for heating a cup of water in a car connects to the car's battery, which has an emf E = 10.0 V and an internal resistance
tatuchka [14]

Answer:

R = 0.93 ohms

Explanation:

Let's start by calculating the resistance of the coil,

V = I ( R + r )

Make R the subject of the above equation.

Hence,

V = IR + Ir

V - Ir = IR

( V - Ir )/I = R

Given that V = 10V

r = 0.07ohms

I = 10A ( this is an assumption )

( 10 - 10×0.07 ) ÷ 10

R = 0.93 ohms

Note: r is the internal resistance, R is the resistance, I is the current and the emf is represented as V. Since current was supposed to be included in the question but it was not, hence it was assumed to be 10A . Meaning whatsoever value is given for current will be substituted into the equation. Thanks
