A 5000 g toy car starts from rest and moves a distance of 300 cm in 3 s under the action of a single constant force. Determine t

sveticcg [70]

Answer:

3.33 N

Explanation:

First, find the acceleration.

Given:

Δx = 3 m

v₀ = 0 m/s

t = 3 s

Find: a

Δx = v₀ t + ½ at²

3 m = (0 m/s) (3 s) + ½ a (3 s)²

a = ⅔ m/s²

Use Newton's second law to find the force.

F = ma

F = (5 kg) (⅔ m/s²)

F ≈ 3.33 N

Determine the velocity (in m/s) of the object at 10seconds. Include a numerical answer accurate to the first decimal place. If n

Answer:

v = 0.5 [m/s]

Explanation:

In order to determine the speed in such a time interval, we must calculate the slope between the last two positions.

The slope of a line is determined by the following mathematical expression.

P₂ = point 2 = (12,12) = (x₂,y₂)

P₁ = Point 1 = (6,9) = (x₁,y₁)

In this specific case, we must see that in the x-axis we have time, and on the y-axis, we have the space axis.

Now using the slope:

$m =\frac{y_{2} -y_{1} }{x_{2} -x_{1} } \\m = \frac{12-9}{12-6}\\m = 0.5$

This slope is equal to the speed (velocity)

v = 0.5 [m/s]

Bob weighs 80 pounds. He ran up the steps which rose 14 feet. Fred weighs 110 pounds. He ran up the same steps as Bob. If both b

pav-90 [236]

Bob gained (80lbs x 14ft) = 1120 ft-lbs of energy.

Fred gained (110lbs x 14ft) = 1540 ft-lbs of energy

Since they both took the same amount of time, Fred's power (rate
of doing work) was greater than Bob's power (rate of doing work).
