- 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 skier leaves the ramp of a ski jump with a velocity of 11.4m/s, 16.2 degrees above the horizontal. The slope below is inclined downwards at 53.3 degrees, and air resistance is negligible. Calculate the distance from the ramp to where the jumper lands (in meters). Calculate the velocity x component just before the landing (in m/s). Calculate the velocity y component just before the landing (in m/s).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?Solve the correct answer and show the complete solution, then illustrate. 4. Nadia walks 4.0km in one direction and 2.0 km in another direction. However, she ends up only three km from where she started. What is the angle between the two directions? *Scale: 1cm=1km
- A basketball player shoots toward a basket 5 m away and 3.0 m above the floor. If the ball is released 1.8 m above the floor at an angle of 52 degrees above the horizontal, what must the initial speed be if it were to go through the basket? Write your answer in m/s with one decimal place. To keep full credit or gain partial credit, you must upload your work in the final question of the midterm.What is a trajectory? What kind of information do you need to predict the trajectory of a particle?1. According to Jules Verne, the Nautilus traveled 20000 leagues under the sea. If it took 1082 days to do this, then what was the submarine's average speed in meters per hour? (1 league = 5556 meters)

Kayla throws the ball at an angle of 40° below horizontal with a speed of 1.2 m/s, and Hafsa catches it 2.4 s later. How far from the base of the dorm does Hafsa stand to catch the ball, in meters? Use g = 10.0 m/s2. Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.Define the term trajectory? What kind of information can be predicted from the trajectory?
- I'm working on a gravity lab. I need to compare the the equations produced by Excel with the kinematic equation for an object in motion. Excel: y= ax2+bx+c Kinematic Equation: y= 1/2gt2+vit+yi Excel created the equation y = -4.7701x2 - 0.5842x + 0.0171. How would that be compared to the kinematic equation? How would I find the acceleration of the object in motion?Directions: Solve for the following problems. One (1) point for illustration or simple sketch, two (2) points for determining the known values, two (2) points for identifying the unknown values, another two (2) points for the equation to be used and three (3) points for showing your solution with boxing your final answer. 1.
