- A skier is on a 25 degree slope and his mass is 80kg. If his constant velocity and the coefficient of kinetic friction between the ski and the snow is 9 m/s and 0.80, respectively, compute his velocity when he has skid 20m from his initial position and a drag force experienced by the skier equivalent to a magnitude of 0.6V^2.arrow_forwardAnd arrows shot horizontally from the height of 4.9 m above the ground the initial speed of the arrow is 45 Meters per second neglecting friction how far away from the archer will the arrow to hit the groundarrow_forwardA motorcycle daredevil plans to ride up a 2.00 m high 26.0° ramp, sail across a 10-m-wide pool filled with hungry crocodiles, and land at ground level on the other side. He has done this stunt many times and approaches it with confidence. Unfortunately, the motorcycle engine dies just as starts up the ramp. He is going 14.9 m/s at that instant, and the rolling friction of his rubber tires is not negligible. Assuming that the local acceleration due to gravity is -9.80 m/s2, calculate the landing point (in m) relative to the 10.0 m edge of the pool. (-1.0 m means he was 1.0 m short and in the pool, +1.0 m means he landed 1.0 m past the edge). The coefficient of rolling friction for rubber on ramp is 0.02.arrow_forward
- Suppose that you loft the ball with an initial speed of v = 16.1 m/s, at an angle of θ = 51.8° above the horizontal. At this instant your opponent is d = 10.7 m away from the ball. He begins moving away from you 0.300 s later, hoping to reach the ball and hit it back at the moment that it is h = 2.02 m above its launch point. With what minimum average speed must he move? (Ignore the fact that he can stretch, so that his racket can reach the ball before he does.)arrow_forwardWhen serving, a beach volleyball player strikes the volleyball (mass = 265 g) at a height of 2.4 metres above the ground. The ball follows the standard path of a projectile, first rising as it passes over the net, and then descending. The opponent receives the volleyball 1.1 seconds later at the same height (2.4 metres above the ground), and at a horizontal distance of 13.5 metres from the server. Answer the following questions assuming there is no effect of air resistance. When the ball was received by the opponent, the horizontal component of velocity (in m/s) was? The vertical component of velocity at take-off and impact (in m/s) can be solved by recognizing that the vertical component of velocity at the point of maximum height in the trajectory of motion is (in m/s)?arrow_forwardIt was found out that on a certain exo planet in Andromeda galaxy, the gravitational acceleration is 19.6 m/s2, and it varies as a function of elevation above the surface given by the expression g=c−bz−az2,wherec= 19.6 m/s2,b= 5.0×10−5s−2, and a= 1.0×10−2m−1s−2.Determine the height above the exo planet’s ground level where the weight of an object will decrease by 1.2 percentarrow_forward
