Answer:
Explanation:
Given
First bicycle travels 6.10 km due to east in 0.21 h
Suppose its position vector is 

After that it travels 11.30 km at
east of north in 0.560 h
suppose its position vector is 

after that he finally travel 6.10 km due to east in 0.21 h
suppose its position vector is 

so position of final position is given by



t=0.21+0.56+0.21=0.98 h


For direction

w.r.t to x axis
Answer:
If the car comes to a sudden stop, your body tends to keep moving forward.
Explanation:
The fraction of the tensile strength which is the stress on the femur is 1.4%.
<h3>What is Tensile strength?</h3>
This is defined as the amount of load or stress that a material can handle before it stretches and breaks.
The femur which is located in the thigh is the largest bone in the body and it exerts a fraction of 1.4% tensile strength through the stress encountered on the femur when the man stands with one leg.

Answer:
Explained
Explanation:
1.Each of the spring scale will read 10N,considering acceleration due to gravity as 10 m/s^2
2.Each of the spring scale will read 10N because each string exerts a force of 10 N to counterbalance the force of 1 kg mass attached to it. This means the tension on the both side of the string is 10 N. So the scale will read 10 N. Also as spring balances are attached in series and kept on table so both spring balances will read same readings.
Answer:
The dart with the small mass will travel the farthest distance.
Explanation:
Acceleration is proportional to force times mass, and inertia is proportional to mass. Inertia is the reluctance of a moving body to stop, and a stationary body to start moving (inertia increses with mass). Assuming they both have the same aerodynamic design, and that they are both launched with the same force applied for the same time duration, the dart with less small mass will accelerate faster than the big mass dart. From this we can see that the small dart will have covered a longer distance before the effect of the force stops, when compared to the more massive dart.
