Your brothers mass is35.6kg and he has a1.3 kg skateboard.what is the combined momentum of your brother and his skateboard if they are going 9.50m/s?
momentum is p=mv so
p(brother)=(35.6)(9.50)and
p(skateboard)= (1.3)(9.50)
solve and add them.
To find the combined momentum of your brother and his skateboard, you need to calculate the momentum of each individually and then add them together.
The formula for momentum is: momentum = mass × velocity.
First, calculate the momentum of your brother:
Momentum of your brother = mass of your brother × velocity of your brother
= 35.6 kg × 9.50 m/s
= 337.8 kg·m/s
Next, calculate the momentum of the skateboard:
Momentum of the skateboard = mass of the skateboard × velocity of the skateboard
= 1.3 kg × 9.50 m/s
= 12.35 kg·m/s
Now, add the two momenta together to get the combined momentum:
Combined momentum = Momentum of your brother + Momentum of the skateboard
= 337.8 kg·m/s + 12.35 kg·m/s
= 350.15 kg·m/s
Therefore, the combined momentum of your brother and his skateboard when they are going 9.50 m/s is 350.15 kg·m/s.
