A 5.00-kg howler monkey is swinging due east on a vine. It overtakes and grabs onto a 6.00-kg monkey also moving east on a secon

d vine. The first monkey is moving at 10.0 m/s at the instant it grabs the second, which is moving at 7.00 m/s. 1) After they join on the same vine, what is their common speed

Answer:

8.36 m/s

Explanation:

From the law of conservation of momentum,

Total momentum of the monkeys before grab = Total momentum after grab

mu+m'u' = V(m+m')................... Equation 1

Where m = mass of the first money, m' = mass of the second monkey, u = initial velocity of the first monkey, u' = initial velocity of the second monkey, V = Common velocity of both monkeys.

make V the subject of the equation

V = [mu+m'u']/(m+m')................ Equation 2

Given: m = 5 kg, m' = 6 kg, u = 10 m/s, u' = 7 m/s

Substitute into equation 2

V = [5×10+6×7]/(5+6)

V = [50+42]/11

V = 92/11

V = 8.36 m/s

A key lime pie in a 10.00 in diameter plate is placed upon a rotating tray. Then, the tray is rotated such that the rim of the p

tatuchka [14]

Answer:

A

The distance in revolutions is $n = 7 \ revolutions$

The distance in degrees is $\theta =2529 ^ o$

The distance in radian is $\theta_{radian } = 44.15 \ rad$

B

$\theta_a = 1.26 \ rad$

Explanation:

From the question we are told that

The diameter of the pie is $d = 10.00 \ in$

The distance covered by the rim is $D = 208 \ in$

The number which the pie is divided into is k = 5

Generally the radius of the pie is mathematically represented as

$r = \frac{d}{2}$

=> $r = \frac{10}{2}$

=> $r = 5 \ in$

Generally the distance covered by the rim is mathematically represented as

$D= 2 \pi r n$

=> $208 = 2* 3.142 * 5 * n$

=> $n = 7 \ revolutions$

Generally converting to degrees

$\theta = n * 360$

=> $\theta = 7 * 360$

=> $\theta =2529 ^ o$

Generally converting to radian

$\theta_{radian } = \frac{\theta * \pi}{180 }$

=> $\theta_{radian } = \frac{2520 * 3.142 }{180}$

=> $\theta_{radian } = 44.15 \ rad$

Generally the angular size of one piece of the pie is

$\theta_a = \frac{2 * \pi }{ k}$

=> $\theta_a = \frac{2 * 3.142}{ 5}$

=> $\theta_a = 1.26 \ rad$

As a van travels along a level stretch of road with constant speed, most of the power developed by the engine is used to compens

babymother [125]

Answer:

64.10937 N

Explanation:

s = Displacement

v = Velocity

F = Force

Converting hp to W

$2.75\times 746=2051.5\ W$

Work

$W=F\times s$

Power

$P=\frac{W}{t}\\\Rightarrow P=\frac{F\times s}{t}$

Now

$\frac{s}{t}=v$

So,

$P=F\times v\\\Rightarrow F=\frac{P}{v}\\\Rightarrow F=\frac{2051.5}{32}\\\Rightarrow F=64.10937\ N$

The friction force acting on the van is 64.10937 N
