By v^2 = u^2 + 2gh
v^2 = 0 + 2 x 9.8 x 15
v = √294
v = 17.15 m/s
Answer:
74.52s
Explanation:
The solution is shown in the picture below
Answer:
294J
Explanation:
The work done by gravity is independent of the horizontal distance. It is only dependent on the vertical height of 15m above its initial position.
The work done against gravity is given by

Given;
m = 2.0kg

Hence;

This planet would be known as pluto
The turning moment on the cover of the book is 0.05 Nm.
Explanation:
Given:
Force applied (F) = 0.5 N
Distance covered (d) = 10 cm
Converting Distance covered from cm to meter we get (d)= 0.1 m
To find:
Turning Moment (M) on the cover of the book = ?
Formula to be used:
Turning Moment (M) = F × d
= 0.5 × 0.1
= 0.05 Nm
Thus the turning moment on the cover of the book is found to be 0.05 Nm
