Acceleration is the way the motion is changing.
Answer:
0.5mv^2=50, v=5, 25/2×m=50, m=50×2/25, So, the answer is 4
Answer:
V = 10m/s for the final velocity.
S = 10m for distance II.
Explanation:
Given the given information:
5m/s2 acceleration
2 seconds Equals time
Because the vehicle begins at rest, its initial velocity is 0m/s.
The first equation of motion would be used to get the ultimate velocity.
V = U + at
We have by substituting into the equation
V = 0 + 5*2
V = 0 + 10
V = 10m/s.
Now, to find the distance covered, we would use the second equation of motion.
S = ut + ½at²
S = 0*2 + ½*5*2²
S = ½*5*4
S = 20/2
S = 10m
Force = 40 - 24 = 16N
Force = mass / acceleration
Acceleration = Force / mass
Acceleration = 16 / 8
Acceleration = 2 m/s^2
Answer:
A: In an observer's reference frame, motion lacking uniform velocity includes motion at constant or variable speed in a circle; and motion of a reciprocating device. Supposing the zero refers to the “uniform velocity” rather than the motion removes the possibility of an object at rest.
