Answer 1

Answer: 2.

Step-by-step explanation:

Given,

Velocity = 7m/s.

Final Velocity = 15m/s.

Time = 4 seconds.

Distance Covered = 15-7/4 = 8/4 = 2.

Answer 2

Answer:

s = 44 m

Step-by-step explanation:

given u = 7 m/s; v= 15 m/s; t= 4s

using v= u+at

15 = 7+a(4)

15-7 = 4a

8 = 4a

a= 2 m/s²

Now to find s we need to use v²-u² = 2as or s = ut+1/2at²

using s= ut+1/2at²

s = 7×4 + 1/2 × 2 × 16

s = 28 + 16

s = 44 m
