Question

4. A vehicle moving with a uniform acceleration of 2 m/s has a velocity of 4 m/s at a
certain time. What will its velocity be
a) I s later,
b) 5 s later?​

Answer 1

Explanation:

u= 4m/s

a= 2m/s^2

a) v 1 sec later

v = u + at

= 4 + 1 x 2

= 6 m/s

b) v 5 secs later

v = u + at

= 4 + 5 x 2

= 14 m/s
