Answer:
24 cm/s
Explanation:
Applying
Pythagoras theorem,
a² = b²+c²............. Equation 1
Where a = resultant, b = vertical component, c = horizontal component
From the question,
Given: a = 26 cm/s, c = 10 cm/s
Substitute these values into equation 1
26² = b²+10²
676 = b²+100
b² = 676-100
b² = 576
b = √576
b = 24 cm/s
Answer:
140.04 m from the stop.
Explanation:
We can divide the motion in two parts:
First, we have an uniformly accelerated motion, using the following formula we calculate the distance traveled in this part:
In the second part, the car decelerates, but we don't know the value of this deceleration. We have to calculate the time spend in the first part, in order to know the time spend on second part:
Recall that total time is 15 s
Now, we calculate the deceleration:
Finally, we find the distance traveled in the second part. In this way, we can know how far does the car travel.
D. because they aren't mixed up evenly
Answer:
In fluid dynamics, an object is moving at its terminal velocity if its speed is constant due to the restraining force exerted by the fluid through which it is moving. ... At this point the object ceases to accelerate and continues falling at a constant speed called the terminal velocity (also called settling velocity).
