Her momentum is 150 kg . m/s.
The formula for momentum is:
p = m x v,
where:
p = momentum
m = mass
v = velocity
Known
m = 30 kg
v = 5 m/s
Momentum
p = 30 kg x 5 m/s = 150 kg . m/s
The principle of conservation of momentum states that the total momentum of a system remains constant if no external forces act on it. In our daily activities, this principle is evident in scenarios such as walking, where the momentum of our body is conserved as we move forward. It also applies to activities like throwing a ball or riding a bicycle, where momentum is transferred between objects but the total momentum of the system remains constant.
Momentum is mass times velocity. The total mass here is 279 kg 279 * 12 = 3348. 3348 newton-seconds/kilogram-meters per second is the momentum.
There are several forces involved while riding a skateboard. The force of friction (air resistance and contact with ground) acting against the motion and the pushing force from when you push off with your foot acting with motion. There are also several normal reaction forces, the weight of the person on the skateboard and the weight of the skateboard on the ground.
In physics, the kinetic energy of an object is the energy that the object possess, due to the fact that the object is moving. When the object/skateboard isn't moving it has no kinetic energy. However when it is given energy such as a push, it would move and keep going until it is stopped by another force, such as a wall.
For a skateboard, friction works between the wheels of the board and the axis, as well as between the wheels of the board and the ground when the board is in motion. Since friction works in a direction opposing motion, it is only in effect when the when the board or the wheels of the board are in motion.

Don't fall.
the trucks
It is called a manual.
j;t
he broke it riding his skateboard
not wery different but yes it is different.much faster and easier to turn.
if you plan on riding it
Skateboarding Mountainboarding
riding solo is about a guy being single and riding solo. so no it is not a traveling song
there is no exact answer to that. but, if he was riding a mega ramp he could at least go 30 mph
they are OK for just riding but if you want to pull any tricks get a good skateboard like blind or venom
