Projectile Motion - A passenger on a boat moving at 1.20 m/s on a still lake walks up a flight of stairs at a speed of 0.50 m/s. The stairs are angled at 45° pointing in the direction of motion as shown. What is the velocity of the passenger relative to the water? Find the Magnitude(m/s) & Direction (above the water) ...

Determine force of air resistance - A fire helicopter carries a 661 kg bucket of water at the end of a 17.0 m long cable. Flying horizontally back from a fire at a constant speed of 44.9 m/s, the cable makes an angle of 32.6 degrees with respect to the vertical. Determine the force of air resistance on the bucket

A box rests on a flatbed truck moving downhill. Find the minimum stopping distance if the box must not slide forward. - A crate rests on a truck which is traveling at speed V= 26 m/sec down a hill inclined at angle b= 8 degrees. The coefficient of friction between crate and truckbed is f= .50. Find the shortest stopping distance such that the crate does not slide forward. SEE ATTACHMENT #1 for ...

string tension - Two masses of 3.5 kg each, connected by a string, slide down a ramp making an angle of 34 deg. with the horizontal. The coefficient of kinetic friction between m1 and the ramp is .33. the coefficient of kinetic friction between m2 and the ramp is .18. I know my acceleration is 3.41 m/s^2 How do I determine the tension of the string? Please show steps

Block M, with block m on top, executes SHM on frictionless surface. Find maximum amplitude for which m remains in place. - A block of mass M= 10 kg is on a frictionless horizontal surface. A small block whose mass is m= 1.0 kg is placed on the larger block. The coefficient of friction between the two blocks is u= .40. The two blocks execute SHM with a period T= 1.5 sec. Find Xm, the maximum amp...
