A hot-air balloon is rising vertically at a constant speed of 15.0 ms-1. A sand bag is released from rest relative to the balloon when the balloon is 35 m above the ground. Calculate the maximum height of the object above the ground. Calculate the time taken to reach the maximum height. Calculate the total time taken for the object to reach the ground.

The particles of an ice cube at 0°c (represented by the blue circles) come in contact with the particles of juan’s hand at 37°c (represented by the orange circles). which diagram correctly represents the temperature of the two substances and the direction of heat flow?

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?
