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...
Two friends are playing golf. The first friend hits a golf ball on level ground with an initial speed of 36.5 m/s at an angle of 31.0° above the horizontal. (a) Assuming that the a ands at the same height from which it was hit, how far away from the golfer, in meters, does it land? Ignore air resistance. What constant acceleration equations will allow you to find the range, given the speed and angle? (Note that, depending on your...
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...
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...
After a golf ball is hit it takes off with an initial speed of 23.4 m/s and at an angle of 42.0° with respect to the horizontal. The golf field is flat and horizontal. Neglecting air resistance how far will the golf ball fly? How high will the golf ball rise? How much time will the golf ball spend in the air? How far would the golf ball fly if the initial speed was doubled? How much time would the...
A golf ball is hit off a 50 m cliff with a horizontal velocity of 30 m/s. How long is the ball in the air?
After a golf ball is hit it takes off with an initial speed of 23.7 m/s and at an angle of 39.0° with respect to the horizontal. The golf field is flat and horizontal. Neglecting air resistance how far will the golf ball fly? How high will the golf ball rise? How much time will the ball spend in the air? How far would the ball fly if the initial speed was doubled? How much time would the ball spend...
A golf ball is hit from ground level and flies through the air over level ground.

A golf ball is hit from ground level and flies through the air over level ground. If it is moving at an initial angle of 52 degrees from the horizontal and the x component of the initial velocity is vz.i 30 m/s, r,l how far does it travel before hitting the ground?
1. A golf ball is hit with an initial velocity of 50.0 m/s at an angle of 34 degrees above the horizontal. If the golf ball lands on the same horizontal level, determine the time it takes the ball to stay in the air. 2. A ball is thrown horizontally, with a speed of 10 m/s, from the top of a 4.9 meter tall hill. How far from the point on the ground directly below the launch point does the...
