Question

A particle starts with velocity 10ms¯¹ the acceleration of particle is 2ms¯² then the velocity of particle at time=4sec is ?​

Answer 1

Answer:

v be the final velocity

u be the initial velocity

v=u+at

v= 10+2(4) = 10+8 = 18 m/s

Answer 2

Answer:

u= 10m/s

a = 2m/s^2

t = 4sec

v = u + at

v = 10 + 2*4

v = 10 + 8

v = 18m/s
