To solve this problem we must use the trigonometric relations, in this case as we have the ramp and the height the concentric trigonometric property to the sin\theta will allow us to find the angle.

The sine of angle A, is defined as

Sin A = \frac{BC}{AC}

Sin \theta = \frac{35}{225}

Sin \theta = 8.9\°

Therefore the angle of elevation is 8.9°

Two students are sitting 1.50 m apart. One student has a mass of 70.0 kg and the other has a mass of 52.0 kg. What is the gravit
algol [13]

Answer:

The gravitational force between them is 1.079\times10^{-7}\ N.

Explanation:

Given that,

Distance = 1.50 m

Mass of one student = 70.0 kg

Mass of other student = 52.0 kg

We need to calculate the gravitational force

Using formula of gravitational force

F=\dfrac{Gm_{1}m_{2}}{r^2}

Where, m₁ = mass of one student

m₂ = mass of other studen

r = distance between them

Put the value into the formula

F=\dfrac{6.67\times10^{-11}\times70.0\times52.0}{1.50^2}

F=1.079\times10^{-7}\ N

Hence, The gravitational force between them is 1.079\times10^{-7}\ N.

A car (mass = 1200 kg) is traveling at 31.1 m/s when it collides head-on with a sport utility vehicle (mass = 2830 kg) traveling
IrinaVladis [17]

Answer:

13.18 m/s

Explanation:

Let the velocity of sports utility car is

-u as it is moving in opposite direction.

mc = 1200 kg, uc = 31.1 m/s

ms = 2830 kg, us = - u = ?

Using conservation of momentum

mc × uc + ms × us = 0

1200 × 31.1 - 2830 × u = 0

u = 13.18 m/s

anygoal [31]

Answer:

2.24 seconds

Explanation:

xf = xo + vo t + 1/2 at^2

45 = 0 + 15 t  + 1/2 (4.5) t^2

   2.25 t^2 + 15t - 45 = 0              Quadratic formula shows  t = 2.24 seconds

Why might a balloon, that is inflated almost to its capacity, pop or explode on an extremely warm day?
REY [17]
On an extremely warm day, the balloon might pop because gases expand the hotter they get, and due to its temperature it is likely to pop if it is, indeed, nearly, if not completely, filled to its capacity.  I hope this helps, have a nice day!
