Question

a body of mass m is being pulled by two strings each having speed of 10 m/s . the two strings are at an angle 60 degree from the center. find the speed with which the mass m rises upwards.

Answer 1

Answer:

Each wave travels from A to B and reflects at B. When each reflected ... The formula that relates tension F in the string and the waves speed v is: ... (b) v = (F/μ)1/2 ; v = [400N/4.00x10-4kg/m]1/2 = 1000 m/s.

Answer 2

Answer:

Let, V be the velocity of mass in upwards direction.

Therefore, component of velocity along the rope = VCosθ

Now, VCosθ=u

Therefore, V=

Cosθ

u
