Answer:
The displacement of the car is 750.15 m
Explanation:
Given;
constant velocity of the car, v = 60 km/h
Convert the velocity to m/s by dividing by 3.6 = (60 /3.6) = 16.67 m/s
time of motion, t = 45 s
The displacement of the car is calculated as;
displacement = velocity x time
displacement = 16.67 m/s x 45s
displacement = 750.15 m
Therefore, the displacement of the car is 750.15 m
Answer:
Explanation:
Given
zero vertical displacement
suppose \theta is the inclination angle and u is the initial velocity
considering horizontal motion
range is given by
where t is the time of flight
Now consider vertical motion
a=acceleration
for zero displacement y=0
substitute the value of t in Range
for maximum vale of must be equal to 1

A skater can spin faster by pulling her arms closer to her body or spin slower by spreading her arms out from her body due to conservation of angular momentum.
What is conservation of angular momentum?
- Conservation of angular momentum is a physical property of a spinning system such that its spin remains constant unless it is acted upon by an external force, or to put in another way, the speed of rotation is constant as long as net torque is zero.
- Angular momentum, sometimes also referred to as spin, is determined by an object's mass, its velocity and distance of an object's mass from the point of rotation.
- The nearer the mass is to its axis point or the more consolidated it is around that axis the greater its velocity.
