Problem Solving. Draw the illustration stated by the problems and show your solutions.
1. A rock I thrown with an initial veloçity of 30 m/s along the vertical and 40 m/s along the
horizontal.
a. What is the velocity at the maximum height?
b. what is the time at the maximum height?
c. What is the maximum height reached?
d. What is the total time of flight?
e.
What is the range of the projectile?.
I need help with this problem and an explanation for the solution described below (Kinematics):
Problem described in image below:
Part A.
For this time interval calculate the average acceleration.
Express your answers in meters per second squared separated by a comma.
Part B.
Find the magnitude of the average acceleration.
Express your answer in meters per second squared.
Part C.
Find the direction of the average acceleration (let the direction be the angle that the vector makes with the +x-axis, measured counterclockwise).
Express your answer in degrees.
You first walk 10 meters at an angle of 30 degrees East of North. Then,you walk 15 meters at an angle of 45 degrees South of East. Assume that East is +x and North is+y, and assume you started at the origin (0,0).
A. Make a graph with x- and y-axes and draw your path on that graph (to scale, or at least asclose as you can get). Start the first vector at the origin, and the second vector at the tip ofthe first vector. Then, draw the resultant vector (their sum).
B. Break each part of the walk into their x- and y-components and then sum them to get thex- and y-components of the resultant vector. Make sure to include units and unit vectors.
C. What is your displacement from where you originally started?
D. If the whole walk took 40 seconds, then what was your average velocity
