What is displacement ?</h3>
A displacement is a vector in geometry and mechanics that has a length equal to the shortest distance between a point P's initial and final positions. It calculates the length and angle of the net motion, or total motion, in a straight line from the starting point to the destination of the point trajectory. The translation that links the starting point and the ending point can be used to spot a displacement.
A point's ultimate location in relation to its original position, or a displacement, can also be defined as a relative position. The instantaneous velocity of an object is the rate at which the displacement changes as a function of time when studying motions of objects throughout time.
Explanation:
a)
height = 2*r =2*45 cm = 90 cm
y = 1/2 * circumference
=1/2 * 2*pi*r
= pi*r
= pi*45
= 141.4 cm
displacement =sqrt ( height^2 + y^2)
= sqrt (90^2 + 141.4^2)
= 167.6 cm
Answer: 167.6 cm
b)
angle ,x = atan (height/y)
= atan (90/141.4)
= 32.5 degree
Answer: 32.5 degree

Hello there!
The answer is the following:
Rapid energy transfer between Potential and Kinetic energy makes roller coasters thrilling.
Potential Energy is the energy related to the vertical position of the roller coaster cart. When it is at the highest point, the Potential Energy is at a maximum.
Kinetic Energy is the energy related to the speed of the roller coaster cart. When the cart is at the highest point, the kinetic energy is at a minimum, but as it begins to go down, the Potential Energy is transformed into Kinetic Energy, making the cart to increase its speed and making it a thrilling experience.
