Momentum = (mass) times (velocity) = (50 + 30) (10) = 800 kilogram-meters per second.

Which has a greater momentum a heavy truck at rest or a moving automobile?
The momentum of any object depends on its mass and its speed. If a car and a bike are both moving at the same speed, then the car has more momentum because it has more mass than the bike. If the car and the bike are moving at different speeds, then we need to know the speeds of each, in order to make any determination about their respective momenta.
Does momentum make a bike move down a hill?
Momentum is the product of mass and velocity which infers motion taking place. If the bike was moving then yes it would make it go downhill. The real culprit would be gravity if the bike was not already in motion. The hill is an incline and the bike is being pulled by gravity down that incline.
How does friction affect a bike rider?
It can affect a rider because depending on how rough the road is the rider will fall.If it is smooth ground then the smoothness will not make the rider fall down all the way on the ground.
Does applying brakes on a bike cause friction?
Yes, and the heat generated is the converted momentum of slowing down.
Would you rather get hit by a bike or a bus explain?
Neither! I'd rather be hit by a bus moving at 2 MPH than by a bicycle going at 40 MPH. But the point of the question is, which has more momentum and kinetic energy? If both the bus and the bike are moving at equal speeds, then you'd stand less chance of serious injury being hit by a bike, because the bike has less mass and therefore less momentum and kinetic energy. However, a lot of bikes have a great many sharp points and corners, while the average city bus is more flat-faced. On the other hand, if you get run over by a bike, it'll get your shirt dirty. If you get run over by a bus, it's likely to crush you.
Will a larger bike always have more momentum than a smaller bike?
No.Momentum is a combination of weight and speed, so something lighter travelling faster can easily have the same momentum as something heavier travelling slower.So, if the bigger bike also is the heavier bike, and the bikes are always travelling at the same speed, then it will have more momentum.Otherwise, anything goes.
A person is riding a bike at 5 m's due west The mass of the rider plus bike is 95 kg What is the magnitude of its momentum?
Momentum = mass x velocity Assuming you mean the rider is riding at 5 m/s, the momentum is 95 x 5, which is 475 kg-m/s
What is the momentum of a 45 kilogram bike going 7.6 meters per second?
Momentum = m V = 45 x 7.6 = 342 kg-m/sec
Is bike a hazard?
Can be. It gives more speed than going on foot, so falling off a bike can hurt more than stumbling when walking. Bicycling often brings the rider out in traffic, where the rider can be run down and run over.
What do you call the driver of a motorcycle?

What makes bike wheels turn?
If you're rolling downhill - gravity. If you're going along on the flat - the pedalling effort of the rider.
Why do Harley riders have a bell tied on their bike?
It's for good luck. A rider can only install the bell on their bike if it is a gift from another rider.
What do you call a professional bike rider?
A Cyclist.
