Q.9 A body starts from rest and travels with an acceleration of 1.5 m/s2. After t seconds its velocity is 6 m/s . Then tis? (a) 10 S (b) 5 s (c) 4 (d) 65

good for her? ? where is the question?

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//

false

hope this : d
