Hey, i just wanted to check my answers with somebody on this question. It's an even number so i can't check with the back of the book, and my final is tomorrow. Here's the question: A soccer ball is kicked 56 degress above the ground at an inital velocity of 12m/s. the mass of the soccer ball is 75 grams. what is the maximum height of the ball? I got 5.05 meters A car is driving up a hill that's 40 degress above the horizontal. Mass of the car is 2000 kg, initial velocity of the car is 22m/s. The mew between the car and the hill is (.36). At 5.05 meters, the soccer ball collides inelastically with the car. What is the velocity of the car and the soccer ball together? I got 21.2m/s Lastly. ignoring the soccer ball being attached to the car: the hypotenuse of the hill is 17m. How much work does friction remove from the system? I got -211837 Joules They're not that hard...but i was wondering if anyone could help me out. THANKS!
