Question

A ball is suspended from the celling of a
tram conr The brakes are applied and
the speed of Con changes uniformly
from 36 km/h to zero in 5 sec
The angle by the ball deviates
from the
vertical (g=10m/s-¹) is.​

Answer 1

Explanation:

a=v/t

= 10/5 [36km/h=36×5/18=10 m/s]

= 2 m/s2

now,, tan theta = a/g = 2/10=1/5

therefore,, theta = 11.30 (app)
