Explanation:
Explanation:
Denise, who is five month old baby is been looked after be a baby sitter as her mother, Marie has to work on the weekends. But Denise is reported to be unwell and cranky for a last few days. And Marie arrives home after getting a call from the baby sitter she found her child unresponsive and pulse was also very feeble. This might be because of the reason that Denise was not well for the last few days and she was suffering from sickness. The baby sitter might not be aware of her health and did not pay much attention to her or taken care of her. Due to the illness she might not have eaten any food or drink any milk or liquid which resulted in dehydration in Denise. So she fainted and was unresponsive.
Answer:
2.22 m
Explanation:
According to literature, the highest abrupt deceleration the human body can experience and survive in a car accident is 250 m/s²
Using the equations of motion,
v² = u² + 2as
v = final velocity of the body = 0 m/s
u = initial velocity of the body = 120 km/h = 120 × 1000/3600 = 33.33 m/s
a = - 250 m/s²
s = ?
0² = 33.33² - (2×250×s)
500s = 1111.1111
s = 2.22 m
The acceleration of a car with the mass of 1,980kg with a net horizontal force of 1,000 N is 0.51m/s².
<h3>HOW TO CALCULATE ACCELERATION?</h3>
The acceleration of a body can be calculated using the following formula:
a = F ÷ m
Where;
- a = acceleration (m/s²)
- F = Force (N)
- m = mass (kg)
According to this question, a car has a mass of 1980kg and horizontal force of 1000N. The acceleration is as follows:
a = 1000/1980
a= 0.51m/s²
Therefore, the acceleration of a car with the mass of 1,980kg with a net horizontal force of 1,000 N is 0.51m/s².
