Conservation of Momentum A collision when two objects end up sticking together can be modelled with the
following equation, if momentum is conserved in the accident then.
a) Momentum of two objects before collision = Momentum of two objects after collision
b) OR
M, V, + MY2 = (M, + M2) V3
So, if a truck with a mass of 3000kg is travelling at +35 m/s to the right, and a car
with a mass of 1000kg is travelling to the left at - 35 m/s.
1) What is the velocity (speed and direction) of the vehicles after the collision if they
are stuck together?
2) Based on your answer, explain which vehicle is safer to be in and why?

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.
