Question

A boat is moved uniformly along a canal

Answer 1

R = √[(200)^2 + (240)^2 + 2×200×240× cos60°]

= √[40000+57600+48000]

= √[145600]

=381.5 or 382 N

For beta angle

200 sin beta = 240 sin gama

Since, both are opposite to each

other and no other forces are there

So they must be equal

200/240 = sin gama / sin beta

Since, gama + beta = 60°

5/6 = sin (60° - beta ) /sin beta

After solving it you will get 33°

And also for gama

5/6 = sin gama /sin (60°- gama)

After solving this gama = 27°

Answer 2

Answer:

yes

Explanation:

a boat is moved uniformly along a canal by two horses pulling with forces p=200 N and Q =240 N acting under an angle a= 60°(Fig. A).
