Nonoy can finish a certain job in 10 days if Imelda will help for 6 days. The same work can be done by Imelda in 12 days if Nonoy helps for 6 days. If they work together, how long will it take for them to do the job? A boat takes 2/3 as much time to travel downstream from C to D. As to return, if the rate of the river’s current is 8 kph, what is the speed of the boat in still water?

A rower wanted to determine the speed of a river's current prior to going down a particular section of the river. She released a tracker into the river. The tracker sent her back the following information: After 5 seconds since the tracker was released into the river the tracker had traveled 5.5 meters. After 10.3 seconds since the tracker was released into the river the tracker had traveled 19.5 meters. Assuming the river was flowing at a constant speed, what was the speed of the current on this section of the river?
A ship headed due east is moving through the water at a constant speed of 10 miles per hour. However, the true course of the ship is 60°. If the currents are a constant 5.0 miles per hour, what is the ground speed of the ship?
As seen in the picture, an airboat is a special type of boatthat has a large fan mounted on the back instead of a motorthat sits in the water. It is used in places where the water isshallow and weedy, so motors that stick down into the watercannot be used. a) Using Newton’s Third Law, explain why the fan needs tobe pointed so the air blows out backwards. b) If the force of the fan pushes the air backwards with 150 N, what is the forward force ofthe air on the boat? If the mass of the boat is 220 kg, and you ignore friction between theboat and the water, find how far the boat will travel in the first minute. c) How can the fan on the airboat be used to change the direction the boat is travelling in?How can it be used to increase or decrease the speed of the boat? d) If the boat is going upstream against a current that has a force of 250 N against themotion of the boat, find the acceleration of the boat if there is a forward force of 360 N fromthe fan. (Remember that the mass of the boat…

Ask Your Question Again 7 of 10 questions left until 1/22/21 Question Hello,I wanna asked if my answer is correct... For A to B I am using Ta+Va=Tb+Vb And I get Ta= 0 since there is no velocity Tb = ½(50)(VB)²=25(VB)² Va=½ks² = ½(2000)(0.6)² =600N Vb=mgh =(50)(9.81)(0.9)= 441.45 Then Vb =2.52 m/s And then using vertical motion from b to c to find t Y=Y initial+(V sin36.87)tBC+1/2a(tBC)² Then t = 0.609s And find d using d=(vcos36.87)t d=1.23m Is my answer and method correct?
