Physics Questions?

Struggling with these physics questions, please explain. Thanks! 1. Ingrid and Greta are on horseback heading to a bonfire celebration at the town square 12.5 miles away. Ingrid challenges Greta to a race for the town square and Ingrid sets off at 15 mph. Greta, thinking Ingrid s horse will tire, sets off at a slower pace of 3 mph. Ingrid decides to rest 4/5 of the way, but falls asleep and loses track of time. Upon awakening, Ingrid quickly sets off at her previous speed of 15 mph, but only manages to reach the town square at the same time as Greta, who kept a even pace the whole entire way. Assume that the trail they follow is perfectly straight. A) Construct and label a velocity-time graph for Ingrid and Greta. B) How far was Greta from the town square when Ingrid resumed her trip? C) How long did Ingrid rest? 2. Two inclined planes are placed adjacent to each other forming an asymmetrical "v" shape. A ball is placed on the steeper of the two and allowed to roll down, accelerating at a rate of 0.500 m/s^2. The ball travels 9.00 m along the plane before reaching the bottom and starting up the second one. It rolls up 15.0 m along this incline before coming to a brief stop. A) How fast was the ball moving upon reaching the bottom of the steeper plane? B) How long did it take to roll down this plane? C) How fast is the ball moving at the moment it has traveled 8.00 m along the second
