Answer:
The belt ramp is moving at 0.047 m/s
Explanation:
Hi!
The equation for the position of an object moving in a straight line with a constant acceleration is:
x = x0 + v0 * t + 1/2 * a * t²
where:
x = position at time "t"
x0 = initial position
v0 = initial velocity
t = time
a = acceleration
If the object moves with constant speed, then, a = 0 and x = x0 + v * t
First, let´s find the lenght of the speed ramp by calculating the distance walked by Clifford.
x = x0 + v0 * t +1/2 * a * t²
x0 = 0 placing the origin of our reference system at the begining of the ramp
v0 = 0 Clifford starts from rest
t = 64 s / 4
a = 0.37 m/s²
Then:
x = 1/2 * 0.37 m/s² * 16 s = 3.0 m
Now that we know the lenght of the speed ramp, we can calculate the speed of the ramp which is constant:
x = x0 + v * t x0 = 0
x = v * t
x/t = v
<u>3.0 m / 64 s = 0.047 m/s</u>

Answer:
1.15 rad/s²
Explanation:
given,
angular speed of turntable = 45 rpm
=
=
time, t = 4.10 s
initial angular speed = 0 rad/s
angular acceleration.
Hence, the angular acceleration of the turntable is 1.15 rad/s²
The planet closest to the sun that has a dense iron core and no moons is : B. mercury
From the options above, only mercury and venus are the one that doesn't have moons. Between the two, mercury is the one that has a dense iron core
hope this helps
Answer:
Explanation:
1. The net force acting on an object is the combination of all of the individual forces acting on it.
2. If two forces act on an object in opposite directions, the net force is the difference between the two forces.
3. If two forces act on an object in the same direction, the net force is the sum of the two forces.
