Question

The momentum of a type of bumper car at an amusement park should not exceed 2100 kg×m/s to ensure the safety of the visitors to the park. If each bumper car has a mass of 780 kg, will the ride be safe if the bumper cars are limited to a top speed of 3 m/s

Answer 1

No, the ride will not be safe according to the standards mentioned in the question because the value of momentum exceeds.

Step-by-step explanation:

Given:

• magnitude of safe momentum of bumper cars,
  `p=2100\ kg.m.s^(-1)`

• mass of each bumper car,
  `m=780\ kg`

• top velocity of bumper car,
  `v=3\ m.s^(-1)`

Now, we find the momentum of the car using the given mass and speed:

`p'=m.v`

`p'=780* 3`

`p'=2340\ kg.m.s^(-1)`

Therefore the ride will not be safe according to the standards mentioned in the question because the value of momentum exceeds.
