Question

the red sled started at a height of 50.0 m and the blue sled started at a height of 25.0 m. the image below was taken right before the two sleds crashed into each other. use the image below to answer the questions. round all numbers to the nearest whole number. red sled mass 100 kg blue sled mass 160 kg red sled speed 31.30 m/s blue sled speed 22.14 m/s the momentum of the red sled is _ kg m/s the momentum of the blue sled is _ kg m/s the _ sled will win the sled war

Explanation:

Step1: Recall momentum formula

The formula for momentum is $p = mv$, where $p$ is momentum, $m$ is mass and $v$ is velocity.

Step2: Calculate red - sled momentum

For the red sled, $m_{r}=100$ kg and $v_{r}=31.30$ m/s. So $p_{r}=m_{r}v_{r}=100\times31.30 = 3130$ kg m/s.

Step3: Calculate blue - sled momentum

For the blue sled, $m_{b}=160$ kg and $v_{b}=22.14$ m/s. So $p_{b}=m_{b}v_{b}=160\times22.14 = 3542.4\approx3542$ kg m/s.

Step4: Compare momenta

Since $p_{b}>p_{r}$, the blue sled has greater momentum and will "win" the sled - on - sled "war".

Answer:

The momentum of the red sled is 3130 kg m/s.
The momentum of the blue sled is 3542 kg m/s.
The blue sled will win the sled war.
