Can someone help me solve these two questions?
Thanks
1) Use the mid-point rule with n = 4 to approximate the area of the region bounded by y = -x^3 and y = -x.
2) A rock is thrown upward with a speed of 48 feet per second from the edge of a cliff 400 feet above the ground. What is the speed of the rock when it hits the ground? Use acceleration due to gravity as -32 feet per second squared.

Can you post any work you've done for these? Where are you getting stuck?
