Find the speed at which Superman (mass=90.0 kg) must fly into a train (mass = 16702 kg) traveling at 75.0 km/hr to stop it. 1.39×10ª km/hr You are correct. Your receipt no. is 163-7690 @ Running into the train at that speed would severely damage both train and passengers. Calculate the minimum time Superman must take to stop the train, if the passengers experience an average horizontal force of 0.510'their own weight. 772.5s The average horizontal force tells you the maximum deceleration of a passenger. With the change in speed in a given time, you can find the deceleration, then get t. Careful with units. Submit Answer Incorrect.

Three skydivers are plummeting earthward. They are initially holding onto each other, but then push apart. Two skydivers of mass 70 and 80 kg gain horizontal velocities of 1.2 m/s north and 1.4 m/s southeast, respectively. What is the horizontal velocity of the third skydiver, whose mass is 55 kg?
Two figure skaters are coasting in the same direction, with the leading skater moving at 5.5 m/s and the trailing skating moving at 6.2 m/s. When the trailing skater catches up with the leading skater, he picks her up without applying any horizontal forces on his skates. If the trailing skater is 50 heavier than the 50-kg leading skater, what is their speed after he picks her up?
A 2000-kg railway freight car coasts at 4.4 m/s underneath a grain terminal, which dumps grain directly down into the freight car. If the speed of the loaded freight car must not go below 3.0 m/s, what is the maximum mass of grain that it can accept?

During a storm, rain comes straight down at a rate of 46.8 kph and perpendicularly hits the roof of a vehicle. Assuming the mass of rain per second that strikes the vehicle's roof is 270 kg/hr. Considering that the rain comes to rest upon striking the car, find the average force exerted by the vehicle's roof on that rain.
