Car designers will more than likely go back to the lab and change certain aspects of the car (Thickness of body, design of the vehicle's frame, etc.), thus making it more durable.

An object of mass 0.50 kg is released from the top of a building of height 8 m. The object experiences a horizontal constant for
liberstina [14]

To solve this problem with the given elements we will apply the linear motion kinematic equations. We will start by calculating the time taken, with the vertical displacement data. Subsequently, with the components of the acceleration, we will obtain the magnitude of the total acceleration, to finally obtain the horizontal displacement with the data already found.

PART A) From vertical movement we know that the acceleration is equivalent to gravity and the displacement is 8m so the time taken to carry out the route would be

h = \frac{1}{2} gt^2

Here,

h = 8 m

g = 9.8 m/s^2

Replacing,

8 = 0.5 * 9.8 * t^2

t = 1.277 sec

PART B) Now, Magnitude of acceleration

a = \sqrt{a_x^2 + a_y^2}

a_x = \frac{1.9}{0.5} = 3.8 m/s^2

a_y = g = 9.8 m/s^2

Thus, magnitude of net acceleration

a = \sqrt{3.82^2  + 9.8^2}= 10.51 m/s^2

PART C) Finally the displacement along horizontal direction is:

s =v_0 t + \frac{1}{2} a t^2

s = 0 + \frac{1}{2} (3.8)(1.277)^2

s = 3.098 m

Therefore the distance traveled along the horizontal direction before it hits the ground is 3.098m

How does temperature affect Brownian motion
Elan Coil [88]

Answer:

Explanation:

Temperature is the measure of average kinetic energy or energy in motion in a molecules. Brownian motion measure kinetic energy or how energetic the motion is and it is proportional to temperature.

Therefore, an increase in Temperature will bring about increase in kinetic energy of brownian motion. It will speed it up.
