Answer:

S = V0 t + 1/2 g t^2

3000 m = 1/2 * 9.8 * t^2 initial speed is zero

t = (6000 / 9.8) ^1/2 = 24.7 sec

A box is at rest on a ramp at an incline of 22°. The normal force on the box is 538 N.

fomenos

Answer: 580 N

Refer to attached figure.

The angle of inclination is 22 degrees

weight (gravitational force) acts downwards.

Normal force is a contact force which acts perpendicular to the point of contact.

The horizontal component (mg cos 22 ) balances the normal force and the vertical component balances the frictional force.

Gravitational force on an object = mg

The normal force $N= mg cos 22$

$\Rightarrow mg =\frac{N}{cos22}=\frac{538 N}{0.927}=580 N$

A 5.0 kg wooden block is in free fall at 10 m/s. What is the Kinetic Energy for the wooden block?

andre [41]

Answer:

250 J

Explanation:

Apply the formula:

K = 1/2.m.v²

K = 1/2.5.10²

K = 1/2.5.100

K = 5.50

K = 250 Joules

But, remember that if the speed is accelerating or not, if it is, then we need to know the point in time that the question is asking for the Kinetic Energy.

In this case, I think it is just a constant speed.
