3.) chipping from the rough, a golfer sends the ball at an angle of 54° with an initial velocity of 13m/s, how far down the green did the ball go?

there are two photos attached for questions #1 and #2.

Zeros that follow non-zeros numbers and are also to the right of a decimal point are significant

Next a skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 15 with the horizontal. the rope moves parallel to the slope with a constant speed of 0.69 m/s. the force of the rope does 800 3 of work on the skier as the skier moves a distance of 8.4 m up the incline. (a) if the rope moved with a constant speed of 2.2 m/s how much work would the force of the rope do on the skier as the skler moved a distance of 8.4 m up the incline? at what rate is the force of the rope doing work on the skier when the rope moves with a speed of (b) 0.69 m/s and (c) 2.2 m/s?
