a ship is travelling due east at 10 km/h. another ship heading 30degree east of north is always due north from the first ship. the speed of second ship in km/h is
2 Answersalways solve by leting two components as v1 in north nad v2(in east....as net b/w north n east).
as original speed at 30deg east of north so, so perpendiculat to it zero velocity.
v1sin30= v2sin60 .........................1
also by relative concept as relative to other ship dirn is north so zero vel along east west direction...it gives
v2=10
thus find the ans...
"like" the post below and click "yes" if it helps
two components is v1 in north nad v2(in east....as net b/w north n east).
as original speed at 30deg east of north so, so perpendiculat to it zero velocity.
v1sin30= v2sin60 .........................1
also by relative concept as relative to other ship dirn is north so zero vel along east west direction...it gives
v2=10
then x=10/sin(30º)=10/1/2=20 km/h

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.

A car loaded with water having total mass 1000 kg moves on a straight horizontal Road starting from rest under the action of a force of 100 Newton. The water spills throw a small hole in the bottom at a rate of 0.1 KG per second the velocity of cart after 300 seconds is nearly.
