Confused on how to find the mass of player 2. two hockey players are traveling at velocities of v1 = 13 m/s and v2 = -17 m/s when they undergo a head-on collision. after the collision, they grab each other and slide away together with a velocity of -3.5 m/s. hockey player 1 has a mass of 122 kg. what is the mass of the other player? you.

here in this type of collision we can use momentum conservation

here we know that

now by above equation of momentum conservation

so mass of the player 2 will be approx 149 kg

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
