A roller coaster car travels down a hill and is moving at 18 m/s as it passes through a section of straight, horizontal track. The car then travels up another hill that has a maximum height of 15 m. If frictional effects are ignored, determine whether the car can reach the top of the hill. If it does reach the top, what is the speed of the car at the top?
what is the maximum mass it can support in freshwater. find the maximum height of the projectile is equal to its horizontal range.
