A particle is following the curved path. Can the normal acceleration speed up or slow down the particle?

No, the normal acceleration will not change the speed of the particle. 

Normal acceleration will only change the direction of motion.

A particle has the following displacements in succession i) 12 m towards east ii) 5 m towards north and iii) 6 m vertically. Find the magnitude of the resultant displacement? 

Here, we have 

x = 12 m ; y = 5 m ; z = 6m

Then, resultant vector is given by, 

r = (x2 + y2 + z21/2

   = ( 122 + 52 + 62)1/2

   = (205)1/2

   = 14.31 m

Find the angle between the vectors: 
straight A with rightwards arrow on top equals straight i with hat on top plus space 2 straight j with hat on top minus straight k with hat on top space and straight B with rightwards arrow on top space equals space minus straight i with hat on top plus straight j with hat on top minus 2 straight k with hat on top


Angle between the vectors is given by, 

 

That is  = cos-1 
This implies, 

 = 600
