Answer with Explanation:
We are given that


We have to find the direction and magnitude of the third force acting on the object.
Resultant force,F=

The object moves with constant velocity .Therefore, net force on object is equal to zero
So,Third force,
Direction,

Angle lies in second quadrant because the direction of third force is opposite to the direction of the resultant force of F1 and F2.
Therefore,

Answer:
Energy lost due to friction is 22 J
Explanation:
Mass of the ball m = 4 kg
Initially velocity of ball v = 6 m/sec
So kinetic energy of the ball 

Now due to friction velocity decreases to 5 m/sec
Kinetic energy become

Therefore energy lost due to friction = 72 -50 = 22 J
Answer:
Explanation:
Given the following data;
Mass = 35 kg
Velocity = 3 m/s
To find the kinetic energy of the child;
K.E = ½mv²
