A boy in a car moving at 10 km/h[N] wants to throw a ball to a girl standing on the right-hand side of the road. He is able tothrow the ball at 20 kin/h. He wants the ban to go straight east, directly to her. (a) Relative to the car, which way should he throw the ball in order to do this?
b) Relative to the ground, how fast will the ball travel to reach her?

Pls explain me in details. I’ll give you brainliest if you give me the first right answer

"an open tank has the shape of a right circular cone. the tank is 6 feet across the top and 5 feet high. how much work is done in emptying the tank by pumping the water over the top edge? note: the density of water is 62.4 lbs per cubic foot."

A5 foot by 5 foot box culvert is buried 6 feet beneath the surface of the ground. a crosssection of this very long culvert (into and out of the page) is illustrated below. assume that the soil in which the culvert is buried has the following properties: jt = 120 pcf, w = 12%, ko = 0.50, ka = 0.33, and kp = 3.00. calculate the total horizontal force per unit length of culvert (fh) felt on one of the vertical faces of the culvert.
