If the stone had been thrown from the clifftop with the same initial speed and the same angle, but above the horizontal, then compare their impact velocities.  a)The impact velocity when throwing a stone above horizontal will be more than the case when throwing a stone below horizontal. b The impact velocities of the two situations will be the same.  c More information is needed to conclude the relative strength of impact velocities. d).The impact velocity when throwing a stone above horizontal will be less than the case when throwing a stone below horizontal.  which option is correct

Recall that the Range equation gives the horizontal distance a projectile can be launched. Suppose there is a slight breeze so that the range equation is modified in the following way: R(0) : = sin(20) – 0.900 R Part A Use Calculus to determine the angle (in degrees) at which the projectile will reach its maximum range. ?

Can you solve the problems and show steps? Thanks.

Is Sandy correct that the moving man did not return to his starting location?   First find area. Then solve the problem by filling in the squares and triangles with the correct meters. Then add all the meters together on both sides. One side should be positive the other negative. Does the final meters add up to 0? If not the man did not return to his starting location. Show all work on the graph.

Please help with parts g and h Two velocity vectors are defined as follows: v1 = 40.0 m/s, 50.0 degrees cw from the +x axis  v2 = 30.0 m/s, 75.0degrees cw from the -y axis     d) Calculate the x- and y-components of v2. Write the vector v2 in terms of its components using unit vector notation.     e) Calculate the x- and y-components of the change in velocity defined as Δv= v2-v1. Write the vector Δv in terms of its components using unit vector notation.     f) Sketch the vector Δv on an x-y grid. Define a relevant angle symbolically whose numerical value you will calculate in the next part.   g) Calculate the magnitude and direction of the vector Δv.   h) Finally, write the vector Δv in terms of its magnitude and direction.

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

Problem: given vector X = 18m, 29 degrees N of W and vector Y = 9m, 80 degress S of E Determine: X-Y (express answer in Unit vectors) *Pls answer with complete solution. *draw a graph/diagram with proper labels *THREE decimal places all final answers *enclose all final answer with a box   ** I'm a little confused on how it can be solve. Can you help me? I would appreciate if you do. Thank you so much

We want to find the coefficient of restitution e between the ball and the floor. We will be able to measure the time of flight between subsequent bounces, but not the velocities before and after each impact. Question 1 a. Using the kinematics equation for position, find a relationship between the time of flight tn and the velocity of the ball after the nth bounce. You should obtain a quadratic equation that has two solutions for the time tm, but only one of them represents the time of flight. b. Using the kinematics equation for velocity and the relationship determined in the previous step, find the relationship between the velocity right after the nth bounce and the velocity right before the (n +1)th bounce? c. Given your answers to the previous parts of this question and the definition of €, find the coefficient of restitution e in terms of the subsequent times of flight tn and tr+1.
