Calculate the speed of an object that tavels 62.43m in 38.4s
TiliK225 [7]
The speed of the object can be calculated using the formula:

Speed = distance/time

The given values are:
distance = 62.43 m
time = 38.4 s

Solution:

speed = 62.43 m / 38.4 s = 1.63 m/s

Therefore, the speed of an object that travels 62.43m in 38.4s is <span> 1.63 m/s.</span>

Chemicals in the air can combine with rain to produce acid rain, which is harmful to the environment. Which of these is most lik
irinina [24]
Hi there!

Normal rain has a pH between 5.0 and 5.5, which is slightly acidic on the pH scale. Acid rain on the other hand has an average pH of 4.0, much more acidic than your average rain.

Therefore, the most likely pH of acid rain would be 4.0.

 Why does a child in a wagon seem to fall backward when you give the wagon a sharp pull forward? 15. What force is needed to acc
slavikrds [6]

Answer:

Force, F = 77 N

Explanation:

A child in a wagon seem to fall backward when you give the wagon a sharp pull forward. It is due to Newton's third law of motion. The forward pull on wagon is called action force and the backward force is called reaction force. These two forces are equal in magnitude but they acts in opposite direction.

We need to calculate the force is needed to accelerate a sled. It can be calculated using the formula as :

F = m × a

Where

m = mass = 55 kg

a = acceleration = 1.4 m/s²

F=55\ kg\times 1.4\ m/s^2

F = 77 N

So, the force needed to accelerate a sled is 77 N. Hence, this is the required solution.
