Answer:
1. 8.3 m
Explanation:
Particle travels 10 m in first 5 seconds
Using equation of motion S = ut + 12at2
10=5u+25a2
Multiply both sides with 8
80=40u + 100a —

ANSWERS :-
Let intial velocity and acceleration are (u) and (a) respectively
For ist second ∆x = Uxt + 1/2axt²
10 = u * 1 + 1/2 * a * 1²
20 = 2u + a ........…(I)
t = (1 + 1 ) = 2sec
displacement is ( 10 + 10 ) + 10 = 30 m
∆x = Ux ,t + 1/2 axt²
30 = u * 2 + 1/2 a(2)²
30 = 2u + 2a
15 = u + a. ...…....(ii)
From equation (I) and (ii) we get
u = 5 m/sec
a = 10 m/sec²
