The raft is traveling down the Mississippi River at a speed of 1.50 m/s relative to the river bank (Fig. 3-49). What is Huck’s velocity (speed and direction) relative to the river bank?

- (I) Huck Finn walks at a speed of 0.70 m/s across his raft (that is, he walks perpendicular to the raft's motion relative to the shore). The heavy raft is traveling down the Mississippi River at a speed of 1.50 m/s relative to the river bank (Fig. 3–42). What is Huck's velocity (speed and direction) relative to the river bank? 0.70 m/s River current FIGURE 3-42 Problem 39.arrow_forwardRomeo is throwing pebbles gently up to Juliet's window, and he wants the pebbles to hit the window with only a horizontal component of velocity. He is standing at the edge of a rose garden 8.0 m below her window and 8.5 m from the base of the wall (Fig. 3–49). How fast are the pebbles going when they hit her window? 8.0 m FIGURE 3-49 Problem 56. e 8.5 marrow_forward(II) A fire hose held near the ground shoots water at a speed of 6.5 m/s. At what angle(s) should the nozzle point in order that the water land 2.5 m away (Fig. 3–36)? Why are there two different angles? Sketch the two trajectories.

If the plane is traveling horizontally with a speed of 250 km/h (69.4 m/s), how far in advance of the recipients (horizontal distance) must the goods be dropped (Fig. 3–38)?

Derive the equation for the range of a projectile fired on level ground, u* sin 20 R where R is the range, 0 is the angle of elevation, and u is the initial velocity. Show that the maximum range is achieved when 0 = 45°.arrow_forward(II) Two planes approach each other head-on. Each has a speed of 780km/h and they spot each other when they are initially 10.0 km apart. How much time do the pilots have to take evasive action?arrow_forward
- (II) An airplane is heading due south at a speed of 688 km/hIf a wind begins blowing from the southwest at a speed of 90.0 km/h (average), calculate (a) the velocity (magnitude and direction) of the plane, relative to the ground, and (b) how far from its intended position it will be after 11.0 min if the pilot takes no corrective action.[Hint: First draw a diagram.arrow_forwardA projectile is launched from ground level to the top of a cliff which is 195 m away and 135 m high (see Fig. 3–56). If the projectile lands on top of the cliff 6.6 s after it is fired, find the initial velocity of the projectile (magnitude and direction). Neglect air resistance.

What initial velocity (magni- tude and direction) does the ball have relative to a person standing on the ground (a) if the hot-air balloon is rising at 3.0 m/s relative to the ground during this throw, (b) if the hot-air balloon is descending at 3.0 m/s relative to the ground? 10.0 m/s FIGURE 3-44 Problem 43.arrow_forward(i) (ii) (iii) A particle is projected horizontally from a point P, h metres above O, with a velocity of V metres per second. The only acceleration that the particle undergoes is the acceleration due to gravity (-g) vertically in a downward direction. There is no horizontal acceleration. h y P V S x Finds the displacement vector of the particle at time t. A package of supplies is dropped from a plane to a disabled sailboat (S) in the ocean. The plane is travelling at a constant velocity of 252 km/h and is 150 m above sea level and directly due west of the disabled sailboat. How long will it take the package to hit the water? (Take g = -10 m/s²) A current is causing the boat to drift at a speed of 1.8 km/h in the same direction as the plane is travelling. Between what two values (distances) can the plane drop the package so that it lands at most 40 m from the disabled sailboat?arrow_forward(i) (ii) (iii) Rylie has a boat which moves at a top speed of 12 ms¯¹ in still water. From point R, he wants to go due north to point D on the opposite side of the river, as shown in the diagram below. D River current 5ms-1 Boat Speed 12ms¹ R Dock E Velocity vector 120 m North Today the current in the river is flowing at 5 ms ¹. From R, he steers the boat due north toward D at top speed. Due to the current he drifts down the river and arrives at point E. Taking R as the origin, write down Rylie's velocity vector in the form xi+yj and find the magnitude of this vector. What is the bearing of Rylie's velocity vector and how far does he travel from R to E ? On what bearing should Rylie have pointed the boat, so that he arrived at the D, with the boat travelling at its top speed?arrow_forward
