How can you say metre cube is a derived unit​
riadik2000 [5.3K]

Answer:

The newton (lowercase n!) is a derived unit because its definition consists of multiplication of three defined base units and nothing else. Its meaning is thus derived, not independently defined.

A boy whirls a stone in a horizontal circle of radius 1.50m and at height 2.00m above level ground. The string breaks, and the s
Eddi Din [679]

Answer:

a_{cp}=162.2m/s^2

Explanation:

The time the stone takes to fall can be calculated considering only the vertical component with the formula:

y=y_0+v_{0y}t+\frac{a_yt^2}{2}

Taking the inital height as 0m and downward direction positive, since it departs from (vertical) rest we have:

y=\frac{gt^2}{2}

Which gives us a time:

t=\sqrt{\frac{2y}{g}}=\sqrt{\frac{2(2m)}{(9.8m/s^2)}}=0.64s

Horizontally, on that time the stone travelled a distance x=10m, which means its horizontal speed was:

v_x=\frac{x}{t}=\frac{10m}{0.64s}=15.6m/s

Since <u>this speed is the tangential velocity</u> while whirling, the centripetal acceleration of the stone was:

a_{cp}=\frac{v_x^2}{r}=\frac{(15.6m/s)^2}{(1.5m)}=162.2m/s^2

How much KE does the car have if it weighs 450kg and moves at the speed of 23 m/s?​
Ray Of Light [21]

Answer:-The formula of to calculate  KE = 1/2 m v^2

so we,

           KE = 1/2 (450kg)(23m/s)^2

           KE = 1/2 ×238050

            KE = 119025

Explanation: In Physics Formulas mean everything.
