Question

a trolley while going down an incline plane has an acceleration of 2 cm square what will be its velocity 3 seconds after the start?​

Answer 1

a=v-u/t

2=v-0/3

2=v/3

2×3=v

6=v

hence the answer is 6 m/s

Answer 2

➧ a ➾ 2 cm/s²
➧ u ➾ 0
➧ t ➾ 3 sec
➧ v ➾ ?

❱ So, v = u + at

v = 0 + (2 cm/s²) × (3 s)
v = 0 + 6 cm/s
v = 6 cm/s ...✔
