A baby crawls from x=1.0m to x=4.25m at an average velocity of 0.226 m/s. How much time did it take? (Unit=s)

postnew [5]

From x = 1.0 m to x = 4.25 m, displacement = 3.25 m

Average velocity of crawling of baby = 0.226 m/s

We know that time taken = Displacement/Time

= $\frac{3.25}{0.226}$

= 14.38 seconds

So, the baby will take a time of 14.38 seconds from x=1.0m to x=4.25m at an average velocity of 0.226 m/s.

Calculate the acceleration of a 2000-kg.

Paraphin [41]

Answer:

$0.25m/s^{2}$

Explanation:

In this problem we use Newton's Second Law formula:

$A= \frac{F}{M}$

F is for the force being applied, in this situation. The 500N is being thrust ed by the engine.

Substitute the force and mass:

$A = \frac{500 N}{2000} ms^{2}$

$A = \frac{1}{4} ms^{2}$

$A = 0.25m/s^2$

how do you solve this problem. A bat flying at 3.7m/s spots an insect 23.8 meters away. How much must the bat increase its speed

RideAnS [48]

Here's how I would do it:

How far does he have to go to catch the bug ? 23.8 meters

How soon does he want to get there ? 1.8 seconds

What speed does he need ? (23.8 m) / (1.8 sec) = 13.222 m/sec

What speed is he flying now? 3.7m/s

How much does he need to increase it ? (13.222 - 3.7) = 9.5 m/s faster
