Question
ANSWER QUICK! Ive read the honor code and it says that their a question can have up to 3 subparts (i.e. part a, b, and c). So please answer all questions.
A train is travelling east along a straight run of track at 66 km/hr. Inside, two siblings 2.2 m apart are playing catch directly across the aisle. The kid wearing a PJ Harvey T-shirt throws the ball horizontally north. The ball crosses the train and is caught 1.2 s later by their little sibling. (Ignore any effects of gravity or friction.)
- Find the magnitude of the ball's velocity in m/s from the little brother's point of view.
- What is the magnitude of the velocity (in m/s) of the ball as seen by someone standing still outside the train?
- What is the angle (in degree) that a stationary observer would say the ball makes during the throw, relative to the direction of the train?

- I don't understand how to do this problem. I tried taking the derivative, but that didn't give me the correct answer. I would really appreciate the help. When a 1984 Alpha Romeo Spider sports car accelerates in the x-direction at the maximum possible rate,its motion during the first 20. seconds is extremely well modeled by the simple equation vx2=(60 m2/s3)t, where t is time in seconds and vx is in m/s. In other words, the squareof teh car's velocity increases linearly with time. What is its acceleration after 3s, assuming that the car starts from rest at t=0 s?arrow_forwardA commuter airplane starts from an airport and takes the route shown in Figure P3.19.

- Could I have help with this physics problemarrow_forwardAt a football game, imagine the line of scrimmage is the y-axis. A player, starting at the y-axis, runs 8.50 yards, back (in the −x-direction), then 15.0 yards parallel to the y-axis (in the −y-direction). He then throws the football straight downfield 55.0 yards in a direction perpendicular to the y-axis (in the +x-direction). What is the magnitude of the displacement (in yards) of the ball? yards (b) What if? The receiver that catches the football travels 64.0 additional yards at an angle of 45.0° counterclockwise from the +x-axis away from the quarterback's position and scores a touchdown. What is the magnitude of the football's total displacement (in yards) from where the quarterback took the ball to the end of the receiver's run?arrow_forwardYou watch an ant crawl around on a piece of paper. The paper is 10.0 inches from top to bottom and 9.60 inches across. When you first look, the ant is at the top of the paper, in the middle of the page. It crawls around finally leaving the paper at the bottom right corner of the paper. Using a coordinate system with the origin at the center of the paper, the +x+x direction pointing to the right, and the +y+y direction point to the top of the page, what angle does the line from the origin to the ant's initial location make with the horizontal? Multiple choice: 43.9° above the horizontal 45° above the horizontal 90° above the horizontal 0° (along the horizontal) 46.2° above the horizontalarrow_forward
