The distance x covered by a particle varies with time t as x 2 =2t 2 +6t+1. Its acceleration varies with x as: 1.x 2. x 2 3. x -1 4. x -3

Question

Khimraj · Answer

x 2 =2t 2 +6t+1 x = (2t 2 +6t+1) 3/2 differentiating wrt t v = (2t+3)/(2t 2 +6t+1) 1/2 angain differentiating wrt t a = -7/( 2t 2 +6t+1 ) 3/2 = -7/x 3 so a x -3 Hope it clears...........................

The distance x covered by a particle varies with time t as x²=2t²+6t+1. Its acceleration varies with x as:
1.x
2. x²
3. x^-1
4. x^-3
