The elevators in the Landmark Tower in Yokohama, Japan are among the fastest in the world. After starting from rest, they reach a maximum speed of 120 meters per minute. It takes the elevator 4.0 seconds to reach maximum speed. What is its acceleration in m/s/s (meters per second per second)?

The acceleration is 30 m/s²

Explanation:

Given that,

Maximum speed = 120 m/s

Time = 4.0 sec

We need to calculate the acceleration

Using equation of motion

Where, v = speed

u = initial speed

a = acceleration

t = time

Put the value into the formula

Hence, The acceleration is 30 m/s²

when earth is in rotational motion around the sun,it displaces from its place.

when a ball is placed on an inclined surface it does both the rotational and circular motion.
