A9.70 kg block sits at rest at the top of a mountain inclined at 12.0 degrees, which is 11.4 km above sea level. a 2.37 kg goose flying with a speed of 73.9 km/h collides into the block. the collision causes the goose to come t a stop, and the block to begin sliding down the mountain. if the coefficient of kinetic friction between the block and the mountain is 0.212, what will the speed of the block be when it is 1.20 km above sea level? 37. bt 73.9 a: 0,212
