Amber applies a net force of 35 N to pull her younger brother (32 kg) in a wagon (3 kg). at what rate does the wagon accerlerate

Physics

Answer:

C. 1.00 m/s^2

Explanation:

We can solve the problem by using Newton's second law:

F=ma

where

F is the net force acting on an object

m is the mass of the object

a is its acceleration

In this case, the net force applied by Amber is F=35 N, while the total mass of the brother+the wagon is

m=32 kg+3 kg=35 kg

Therefore, we can re-arrange the previous equation to find the acceleration:

a=\frac{F}{m}=\frac{35 N}{35 kg}=1.00 m/s^2

Which sequence shpes the steps of the proces of science in an order in which they might occur?
ivanzaharov [21]

The steps of the process of science in an order in which they might occur

exploration >> hypothesis >> prediction >> experiment.

The correct option is D.

<h3>Explanation:</h3>
  • A series of sequential steps are included in the scientific method, which is how knowledge in the scientific field is acquired.
  • When a question arises from observing the natural world, a hypothesis is a predetermined explanation of the question.
  • Experimental and/or observational procedures must be used to test a hypothesis and determine whether it is true or false.
<h3>What are some fundamental scientific procedures?</h3>

When scientists conduct research and study, they use specific science process skills. The thinking processes that scientists, teachers, and students use when conducting science include observing, categorizing, communicating, measuring, inferring, and predicting.

The Jamaican bobsled team was moving at a velocity of 50 m/s, then they hit the brakes on their sled to decelerate at a uniform
atroni [7]

Answer:

The time it took the bobsled to come to rest is 10 s.

Explanation:

Given;

initial velocity of the bobsled, u = 50 m/s

deceleration of the bobsled, a = - 5 m/s²

distance traveled, s = 250 m

Apply the following kinematic equation to determine the time of motion of the bobsled;

s = ut + ¹/₂at²

250 = 50t + ¹/₂(-5)t²

250 = 50t - ⁵/₂t²

500 = 100t - 5t²

100 = 20t -t²

t² - 20t + 100 = 0

t² -10t - 10t + 100 = 0

t (t - 10) - 10(t - 10) = 0

(t - 10)(t - 10) = 0

t = 10 s

Therefore, the time it took the bobsled to come to rest is 10 s.
