Answer : whats your question v
Answer:
The answer to your question is: a = 2 m/s²
Explanation:
I' ll solve it in this way, tell me if I'm right. Because we need to consider that in the moon there is no gravity.
Data
F = 50 N
a = 4.0 m/s²
Moon
F = 25 N
a = ?
Formula
F = m x a
First, calculate the mass
m = F / a
m = 50 / 4
m = 12.5 kg
Now, calculate the acceleration
a = F / m
a = 25 / 12.5
a = 2 m/s²
Answer:
The angular speed is 0.83 rad/s.
Explanation:
Given that,
Mass of disk M=49 kg
Radius = 1.7 m
Mass of child m= 29 kg
Speed = 2.6 m/s
Suppose if the disk was initially at rest , now how fast is it rotating
We need to calculate the angular speed
Using conservation of momentum
Put the value into the formula
Hence, The angular speed is 0.83 rad/s.
net force= the sum of all the forces acting on the object
the frictional force is opposite to the direction of motion of the object
If the object moves to the right (positive) then the friction force moves to the left (negative).
so the net force: 50 N - 5 N = 45 N (B)
Answer:
Observational data collected by doppler radar, radiosondes, weather satellites, buoys and other instruments are fed into computerized NWS numerical forecast models.
