Ascrotal muscle that contracts in response to cold environment temperature is the

The correct answer is Cremaster muscle.

The cremaster muscle elevates and lowers the testis in order to monitor its temperature. When a man comes into the surrounding of colder temperature, the muscle makes the testis to move against the body. The more the testis comes closer to the body, the less it comes in contact with the cold air.

acceleration= v2-v1/t so 8m/s-3m/s / 3s =to 8/3 or

2.67 m/s^2
