A golf ball is hit off a tee at the edge of a cliff. Its x and y coordinates as functions of time are given by x = 16.6t and y = 3.84t − 4.90t2, where x and y are in meters and t is in seconds. (d) Next use unit-vector notation to write expressions for the position, the velocity, and the acceleration of the golf ball at t = 3.06 s. I need help with part d. A golf...
A golf ball is hit off a tee at the edge of a cliff. Its x and y coordinates as functions of time are given by x = 17.5t and y = 3.80t-4.90t. where x and y are in meters and t is in seconds (a) Write a vector expression for the ball's position as a function of time, using the unit vectors i and j. (Give the answer in terms of t.) By taking derivatives, do the following. (Give...
A golf ball is hit off a tee at the edge of a cliff. Its x and y coordinates as functions of time are given by the following expressions. x- (20.0 m/s)t y (5.20 m/s)r-(4.90 m/s2)r2 (a) Write a vector expression for the ball's position as a function of time, using the unit vectors i and j. (Use the following as necessary: t.) (b) By taking derivatlves, obtain an expression for the velocity vector v as a function of time...

Please answer the last 4 bullet points step by step. Again the last 4 bullet points. k III.pdf 1) Up until now we have always ignored air resistance. We should now add . Let us just think of simple 1-dimensional problem, dropping a ball of mass m from a height H but 2 with air resistance. We can model the air resistance as a force proportional to the velocity, fair = bu. The coefficient b is a constant. (For this...
10. + 0/3 points | Previous Answers SerPSET9 12.P.021. My Notes + Ask Your Teacher John is pushing his daughter Rachel in a wheelbarrow when it is stopped by a brick 8.00 cm high (see the figure below). The handles make an angle of a = 20.0° with the ground. Due to the weight of Rachel and the wheelbarrow, a downward force of 405 N is exerted at the center of the wheel, which has a radius of 15.0 cm....
