What must be the force between the vehicle
and road if the vehicle is to be stopped with a
negature acceleration of 1.7 mS-2 ?
​

Answer 1

Answer:

An vehicle has a mass of 1500 kg. What must be the force between the vehicle and the road if the vehicle is to be stopped with a negative acceleration of 1.7 ms⁻²? ( Ans: 2550 N in a direction opposite to that of the vehicle)

Explanation:

Answer 2

$\star{\underline{\underline{\sf\red{ Solution:-}}}}$

Given:

• Mass (m) = 1500 kg
• Acceleration (a) = -1.7 m/s²

$\star{\underline{\underline{\sf\red{ To\:Find:-}}}}$

• Force must be applied on vehicle?

$\\ \star{\underline{\underline{\sf\red{ Formula:-}}}}$

According to the second law of motion,

$\\ \bullet{\boxed{\sf{ F = m \times a} }}$

$\colon\implies{\sf{ F = 1500kg \times (-1.7 ms^{-2}) }}$

$\colon\implies{\underbrace{\sf{ \: \: -2550\:N \: \: }}}$

Therefore,

A force of 2550 N act on the vehicle in a direction opposite.
