If the mass of the skateboard doubled but the net force on it remained constant what would happen to the skateboard's acceleration?
The force equal mass times acceleration, if force remains the same, and mass is doubled, then acceleration must be cut in half.
Which has the greater mass a heavy truck at rest or a rolling skateboard which has greater momentum?
The truck has the most mass, but because it is at rest, the skateboard has the most momentum.
You push yourself on a skateboard with a force of 30 N and accelerate at 0.5 ms2 Find the mass of you and the skateboard together?
To find the mass, you can use Newton's second law, which states that force equals mass times acceleration (F = ma). Rearranging the formula to solve for mass, the mass of you and the skateboard together is given by mass = force/acceleration. Therefore, the mass would be 60 kg (mass = 30 N / 0.5 m/s^2).
Which has a greater momentum a heavy truck at rest or a moving skeatboard?
A moving skateboard has greater momentum than a heavy truck at rest. Momentum is determined by both the mass and velocity of an object, so even though the truck may have more mass, the skateboard's velocity contributes more to its momentum.
What is the force a skateboard exerts on you if your mass is 60k and you push on the skateboard with a force of 60n?
The force the skateboard exerts on you would be equal and opposite to the force you exert on the skateboard, according to Newton's third law. Therefore, the skateboard would exert a force of 60N on you.
If a person throws a ball on a skateboard the skateboard will go backward at the same rate as the ball slower than the ball or faster than the ball?
The answer is tied up with conservation of momentum; momentum is the product of velocity and mass, so assuming the ball is lighter than the skateboard and rider, the skateboard will go backwards slower than the ball.
Where might one purchase a vintage skateboard?
There are many retailers that offer vintage skateboards. The best place to find a specific vintage skateboard, is either with the manufacturer themselves, or from mass online retailers such as Amazon and EBay.
If a force of 20 newtons causes a skateboard to accelerate at a rate of 10 meters per second per second what is the mass of the skateboard?
F = M A20 = 10 MM = 20/10 = 2 kilograms
How do you increase the kinetic energy of a skateboard?
Since kinetic energy depends on mass and speed, you can increase either of these.
Does a sock lying on a dresser have more potential energy then a skateboard on the floor?
No, the skateboard on the floor would have more potential energy due to its higher mass and distance from the ground. Potential energy is determined by an object's position and height above the reference point, so in this case, the skateboard would have more potential energy.
Which is A student weighing 45kg runs down a slope and suddenly jumps with a speed of 3 m s onto a stationary skateboard The student and the skateboard move with a velocity of 2.7 m s What is the mass?
The mass of the skateboard is 11.25 kg. This can be calculated using the principle of conservation of momentum, where the momentum of the student before jumping is equal to the momentum of the student and skateboard after jumping.
What kind of energy does a skate board have?
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.
