Acar of mass m travels around a particular highway curve at speed v. if a truck of mass 3 m travels around this same corner but at half the speed of the car, then the new centripetal force required must be what multiple of the original force?

Explanation:

m = Mass of car

3m = Mass of truck

v = Velocity of car

= Velocity of truck

r = Turn radius

Centripetal force is given by

For car

For truck

Dividing the forces we get

So, the multiple of the original force is

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
