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

Answer:

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

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:

$p'=m.v$

$p'=780\times 3$

$p'=2340\ kg.m.s^{-1}$

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