Question

While accelerating from a stopped position a 1000 kg car is subject of 6.1 x 103N. Determine the speed of the car 8s after start A. 15.8 m/s B. 48.8 m/s C. 60 m/s D. 80 m/s​

Answer 1

Explanation:

i think the answer is C that the answer!

Answer 2

Mass of car = 1000 kg

Force applied on car = (6.1 × 103) N

Then,

• Acceleration of car = Force/Mass

$\frac{1000}{6.1 \times 103} \\ \\ = > 1.59 \: \: \: = 1.6 \: \: \tt{ms}^{ - 2}$

Here,

• Initial speed of car = 0 m/s
• Time of motion = 8 sec

Thus,

$\textsf{ Speed of Car after 8 second } = 1.6 \times 8 \\ \\ = > 12.8 \: \: \tt {ms}^{ - 1}$
