A 1.35 ×103 kg car rounds a circular turn of radius 11.9 m. The acceleration of gravity is 9.81 m/s 2 . If the road is flat and

the coefficient of static friction between the tires and the road is 0.67, how fast can the car go without skidding? Answer in units of m/s.

Answer:

velocity = 8.84 m/s

Explanation:

given data

radius r =  11.9 m

acceleration of gravity g = 9.81 m/s²

static friction μ = 0.67

to find out

how fast can the car go without skidding

solution

we get here velocity that is car go without skidding is express as

force = \frac{mv^2}{r}

force = μ × mg

μ × mg = \frac{mv^2}{r}

v² = μ × r × g

v = \sqrt{\mu *r*g}    ..................1

v = \sqrt{0.67 *11.9*9.81}

v = 8.84 m/s

velocity = 8.84 m/s

Solve P= a+b+c for B
Dahasolnce [82]

Answer:

b = - a - c + p

Explanation:

P= a+b+c : move the b over to the other side.

-b + p = a + c : move p over the other side.

-b = a + c - p : now just convert the a + c - p into,

b = -a - c + p

1 7 points If you take less time to perform a task, you have less power output. O True O False​
horsena [70]

True

The rate at which work is done is referred to as power. A task done quite quickly is described as having a relatively large power. The same task that is done more slowly is described as being of less power. Both tasks require he same amount of work but they have a different power.

If m1 is 50 kg and has a velocity of 4 m/s, and m2 is 75 kg and has a velocity of -1 m/s, then what would be the final velocity
MAXImum [283]

The final velocity of object 2 is: 3 m/sec

<h3>What is the conservation of mass?</h3>

According to the rule of conservation of mass, no atoms are created or destroyed during a chemical process. Instead, the atoms combine in a variety of ways to create goods. This explains why each element has the equal amount of atoms on both sides of an equation with balanced symbols.

According to conservation of mass,

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

Given that,

m₁ = 50 kg

m₂ = 75 kg

u₁ = 4 m/s

u₂ = -1 m/s

v₁ = -2 m/s

v₂ = ?

Now, putting the values,

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

(50 × 4) + [75 × (-1)] = [50 × (-2)] + (75 × v₂)

or, 125 = -100 + 75 v₂

or, 75 v₂ = 225

or, v₂ = 3 m/sec.
