The two forces F1 and F2 inclined at an angle of 60 degrees with each other is acting on a body of mass 5kg. If F1 = 20N and F2 = 15N, what will be the magnitude and direction of acceleration?
2 Answers
x direction : f2+cos 60 xf2 =15+10=25=m A(x direction)
Ax in x direction is 25/5 =5m/s
in y
20 sin 60 = m Ay
Ay=2(3)^(1/2)
net acc is A:
A^2 = 25+12
A=(37)^(1/2)
MAGNITUDE OF FORCE
F=( (20)2 +(15)2 ) 1/2
F=25N
FOR DIRECTION
Tan C = 16sin 60/20+16cos 60
WHERE C IS ANGLE BETWEEN 20N FORCE AND RESULTANT FORCE

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.
