Question

The initial velocity of a body moving along a straight line is 8u. it has a uniform acceleration 6 ms-2. the distance covered by the body in the 6th second of its motion is 41 m. the value of

Answer 1

Answer:

u=41/48=0.85

Explanation:

Velocity=distance/time.

8u=41/6

u=41/48

Therefore u=0.85

Answer 2

Answer:

Explanation:

Answer:

Dnth=u+a/2(2n-1)

• 41=8u+6/2(12-1)
• 41=8u+3(11)
• 41-33=8u
• u=8/8
• u=1m per sec

Explanation:

d means distance

u means initial velocity

a means acceleration

n means no. of seconds

hope u got right ans.
