a 16.0 kg cart is being pulled by a 95.4 N force to the right and a 36.0 N force to the left. What is the acceleration of the ca

Inga [223]

Answer:

The cart's acceleration is $\approx 3.71\,\,\frac{m}{s^2}$

Explanation:

Let's start by finding the net force acting on the cart, and then find its acceleration using Newton's 2nd Law.

Net force = 95.4 N -36.0 N = 59.4 N

Now, since we know the cart's mass, we can use Newton's 2nd Law to find the cart's acceleration:

$F=m\,*\,a\\a=\frac{F}{m} \\a=\frac{59.4}{16} \,\,\frac{m}{s^2} \\a\approx 3.71\,\,\frac{m}{s^2}$

If the frequency of q of a trait is 0.4, what is the frequency of p?

lianna [129]

In genetic traits, p and q represent the relative probabilities of the two alleles manifesting. If these two are the only options (ex. a dominant one and a recessive one), then the probabilities of both must sum up to 1. In this case, since we are given that q = 0.4, then p + q = 1, p + 0.4 = 1, and p = 0.6.

the pilot of a new stealth helicopter, which has a mass of 15000 kg and was traveling at 180 m/s, accelerated to 250 m/s in 6 s

nirvana33 [79]

Answer:

Force = 175000 newtons

Final momentum = 1050000 N*S

Explanation:

We know that force is equal to Mass * acceleration

We also know that the mass of object is 15,000kg.

We know acceleration is (change in velocity)/time

Our initial velocity is 180m/s

our final velocity is 250 m/s

the time it took was 6 seconds

our change in velocity is 250 - 180 = 70

the time it took was 6 seconds

a = 70/6 = 11.67 m/s^2

So we can calculate force, by doing Mass * Acceleration, which is 15,000 * 11.67

Force is 175000 Newton's

Momentum is calculated by Velocity * mass or Force * time

we could do either one

velocity * mass way

we are given final velocity is 250 m/s, and that the initial velocity is 180 m/s. We first have to find the change in velocity by subtracting final and initial and get 70, and then we multiply that by the mass, which is 15000 kg.

we multiply them together and get 1050000 Kg*m/s

Force * time way

We just calculated the force above, and got 175050 newton's. from that we just multiply by the time, which is 6 seconds

and we get a result of

1050000 Newton*seconds

*** remember newton*seconds is the same as kg*m/s

Determine the average acceleration for x(t)=19t^2+7t^3 for a time interval between 3 and 9 seconds

AleksandrR [38]

Answer:

290

Explanation:

Average acceleration is the change in velocity over change in time.

First, find the velocity by taking the derivative of position.

v(t) = dx/dt

v(t) = 38t + 21t²

At t = 3 and t = 9:

v(3) = 303

v(9) = 2043

So the average acceleration is:

a = Δv / Δt

a = (2043 − 303) / (9 − 3)

a = 290

Use appropriate units.
