Answer 2

Answer:

Option (c) i.e. 1725 m, 190 m/s

Explanation:

Given that

• u = 40 m/s
• a = 10 m/s²
• t = 15 seconds

We need to find the distance travelled and the final velocity.

Formula in use

• v = u + at
• s = ut + {(at²)/2}

Solution

v = u + at

Therefore v = 40 + (10x15)

Therefore v = 40 + 150

Therefore v = 190 m/s

s = ut + (1/2 at²)

Therefore s = (40x15) + (10x15x15 / 2)

Therefore s = 600 + 1125

Therefore s = 1725 m

Hope you find this in order. If yes then like it and mark me as BRAINLIEST. Thank you
