Explanation:
Centripetal force is mass times centripetal acceleration:
F = m v² / r
If force is doubled while mass and radius are held constant, then velocity will increase.
2F = m u² / r
2 m v² / r = m u² / r
2 v² = u²
u = v√2
So the velocity increases by a factor of √2.

The momentum of the bumper car after the collision is 1,040 kgm/s.
<h3>
Momentum of bumper</h3>
The change in momentum of the bumper is calculated as follows;
P = v(m1 + m2)
P = 8(55 + 75)
P = 1,040 kgm/s
The momentum of the bumper car after the collision is 1,040 kgm/s.
The direction is still the same.
