Answer:
32 m/s²
Explanation:
Centripetal acceleration is:
a = v² / r
Given v = 8 m/s and r = 2 m:
a = (8 m/s)² / (2 m)
a = 32 m/s²
Apparent magnitude because Apparent is kinda like when something is obvious. So that's how I think of it.
Answer:
speed = distance/time so v = 100/50 m/sec = 2 m/sec.
D = 2T ⇐formula for distance, in meters, for trip duration in T seconds, ASSUMING CONSTANT SPEED.
If the surface between them is the same, then the largest force exerts the body with the largest mass, ie 8 kg
Answer:
12N to the right.
Explanation:
There is a force of 12N upwards and a force of 12N downwards: these cancel out.
Assign a negative value to forces towards the left, and a positive value to the forces towards the right: -3N and +15N
Combine them: -3N+15N = 12N
The net force has a magnitude of 12N, and since our answer was positive, it acts towards the right.
