a car of mass 1600 kg collides head on with a parked truck of mass 2000 kg. Spring mounted bumbers ensure that the collision is essentially elastic. If the velocity if the truck is 17 kg/h after the collision and the cars final velocity was -2.25 kg/h. What was the initial speed of the car? (m1v1,i + m2v2,i = m1v1,f + m2v2,f)

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~

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.
