The best answer for this question is generally the best period to look for crabs is for the duration of the full moon, this is as a result of most invertebrates being nocturnal and being more effortlessly spotted and being fascinated to light sources.

A 1.5-kilogram cart initially moves at 2.0 meters
Anon25 [30]

             Acceleration = (change in speed) / (time for the change)

Change in speed = (speed at the end) minus (speed at the beginning.

The cart's acceleration is

                               (0 - 2 m/s) / (0.3 sec)

                           = ( -2 / 0.3 ) (m/s²)  =  -(6 and 2/3) m/s² .

Newton's second law of motion says

                             Force = (mass) x (acceleration) .

For this cart:      Force = (1.5 kg) x ( - 6-2/3 m/s²)

                                       = ( - 1.5 x 20/3 ) (kg-m/s²)

                                       =      - 10 newtons .

The force is negative because it acts opposite to the direction
in which the cart is moving, it causes a negative acceleration,
and it eventually stops the cart.

A 5.5 kg bowling ball initially at rest is dropped from the top of a 12 m building. It hits the ground 1.75 s later. Find the ne
Thepotemich [5.8K]

We are given that:

m = 5.5 kg

d = 12 m

t = 1.75 s

Using the distance formula, we can get the acceleration of the ball:

d = (1/2) a*t^2

Rearranging:

a = 2d/t^2 = 2*(12 m)/(1.75 s)^2

a = 7.837 m/s^2

 

<span>Using Newton’s 2nd law, force is defines as:</span>

F = ma

F = 5.5 kg (7.837 m/s^2)

<span>F = 43.10 N</span>
