This force is centripetal force. it is the force that will hold the rider in the circular path and prevent him from skidding off. It is equal to the friction between the tyres and the road if no banking has been done on the road at the corner.
Answer:
3.67 rad/s
Explanation:
L = Length of meter stick = 1 m
r = Distance at which the bullet will hit the stick =
m = Mass of bullet = 3 g
M = Mass of stick = 270 g
= Velocity of bullet = 250 m/s
= Velocity of bullet leaving = 140 m/s
Initial angular momentum
Final angular momentum of the system
Since, angular momentum is conserved we have
The angular speed is the stick spinning after the collision is 3.67 rad/s
Displacement can be defined as the overall change in the position of the object. The displacement of the car in 5 hrs is 0 km.
Displacement:
It is a vector quantity that is defined as the overall change in the position of the object.
The formula for displacement is:
Where,
- total displacement
- final position
- initial position
In the given graph:
- Car displaces 15 km in 2 hrs
- Car displaces 20 km in 4 hrs.
- The car moves back to the initial position in 5 hrs.
Therefore, the displacement of the car in 5 hrs is 0 km.

Because of friction, net work on the crate is less. ∆KE = Net work = net force x distance = (100 N – 70 N)(10 m) = 300 J.
Answer:
The answer is "4-5-6 because the bank is growing too quickly in the beginning of its turn".
Explanation:
The S-turns is also known as the reference technique, in which the ground track of the aircraft on both sides of a defined ground-based straight-line distance represents 2 different but equivalent circles.
Throughout the S-turns, on either side of the road, a progressively smaller half-circle is formed, and this turn does not stop until the road or reference line is crossed during the early part of the turn, the twists increase too quickly.
