PHYSICS PLEASE HELP
a. Draw a force diagram
b. The skier has a mass of 76.6 kg and the coefficient of kinetic friction between the skier and the snow is 0.15. The angle the hill makes to the horizontal is 38 degrees and the distance the skier glides down the hill is 40.5 m. Answer the following questions based on this information.
What is the magnitude of the normal force on the skier as they glide down the hill? Show your work.
c. What is the magnitude of the force of friction on the skier as they glide down the hill? Show your work.
d. What is the acceleration of the skier as they glide down the hill? Show your work.
e. What is the speed of the skier when they reach the end of the straight section of the hill? Show your work.
f. How many seconds does the skier take to reach the end of the straight section of the hill? Show your work.

Isobars are lines of constant or equal pressure on a weather map. they can be used to find areas of low or high pressure over a broad area, and they can tell us how intense the system may be. on weather maps, you may have noticed areas that have a large l or h over a region with lines circling around them. the l stands for low pressure and h stands for high pressure. the lines circling them are isobars. check out the pressure system and isobars over georgia and florida. what is the present weather in this area ? a) clear and sunny b) cold and cloudy c) changing weather d) lots of precipitation
