Question

Starting from rest, the acceleration of a particle is a=2(t−1). The velocity of the particle at t=10s is:-

Answer 1

Answer:

v = u + at

[ a = 2 ( t - 1 ) ]

v = 0 + 2 ( t - 1 ) * 10s

v = 2t - 2 * 10s

v = 2t - 20s

[ t = 10s ]

v = 2 * 10s - 20s

v = 20s - 20s

v = 0

hope it helps

Answer 2

Answer:

v = 20(t-1)

Explanation:

v=u+at

v = 0 + (2 (t-1)) × 10

v = 20 (t-1)
