Rex and Tex board the bumper cars at the local carnival. Rex and their car weigh 211 kg while Tex and his cart weigh 217 kg. Rex is moving at a full speed of 2.05 m/s when they rear-end Tex who is at rest in their path. Tex and his car lunge forward at 1.40 m/s. Determine the post-collision speed of Rex and their car.

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
