a)Draw a free body diagram for a kayaker paddling with the rivers current at constant velocity. If the water pushed forward on the paddle with 200N of fotce and the mass of the boat/paddler system is 150kg, with what force does the water push horizontally on the hull of the boat? b)Now, draw a free body diagram for a kayakrr in the air just after going over a waterfall, what information do you need in order to calculate his acceleration?
A gazelle jumps with a speed of 10 m/s at an angle of 60 degrees from the horizontal. You want to calculate the total time that the gazelle spends in the air (to the top of the trajectory and back to the ground). In using one of the kinematic equations, which number do you use for the velocity component? Select onver a. 5.0 m/s b. 8.7 m/s. O c. 10m/s. Next page PULSE 2/9/18 3 5 9 with a speed...
10) A kayaker can paddle at 2 m/s. She wants to cross a 50 m wide river that is flowing at 0.75 m/s. If she points her kayak straight across and moves 2 m/s relative to the water, what a. is her net velocity vector relative to the shore? How far downstream will she be when she reaches the other side? She wants to paddle straight across. What angle upstream should she point the b. c. kayak and how long...
a bullet is fired at an angle θ = 60 degrees with velocity 30m/s. What is the time interval to reach the maximum height?
27. A ball is kicked with a velocity of 30m/s at an angle of 60 degrees relative to the horizontal. Assuming no air resistance ) What are the initial Vx and Vy components of the projectile shot? b) What will be the maximum vertical height the ball reaches in meters? c) How long in seconds will it stay in the air (hang time)? d) What will its velocity be at its maximum height? e) Calculate the total horizontal distance( range)...
A kayaker needs to paddle north across a 90 m wide harbor. The tide is going out, creating a tidal current that flows to the east at 1.8 m/s. The kayaker can paddle with a speed of 2.8 m/s. (a) In which direction should he paddle in order to travel straight across the harbor? ° west of north (b) How long will it take him to cross? s
A kayaker needs to paddle north across a 100 -m wideharbor. The tide is going out, creating a tidal current that flowsto the east at 2.0 m/s. The Kayaker can paddle with a speed of3.0m/s. a. In which direction shoule he paddle in order to travel straightacross the harbor ? b. How long will it take him to cross ? A body diagram and step by step precise solution willgive me a better understanding .. thanks for you help..
An object is launched at a velocity of 33 m/s in a direction making an angle 34 degrees upward with the horizontal. What is the total flight time of the object ? (assume g = 9.81 m/s2)
A ball is thrown with an initial velocity which forms an angle alpha = 60 degrees with the horizontal, of magnitude v0= 10m/s. How far has the ball traveled in horizontal direction from where it was thrown when it reaches its highest point.
a projectile is fired with an initial speed of 2000 m/s at an angle 21 degrees above the horizontal. if air resistance is neglected , what is the velocity in m/s at the highest point of trajectory ?
