Question

3)
An automobile vehicle has a mass of 1500 kg. What must be the force between the
vehicle and road if the vehicle is to be stopped with a negative acceleration of 1.7 m
S-2?​

Answer 1

Answer :-

Given :-

• Mass of vehicle = 1500 kg
• Acceleration = -1.7 m/s²

To Find :-

• Force

Solution :-

We know that,

Force = Acceleration × Mass

Here, we are given both acceleration as well as mass. So, we can simply find the force by substituting the value in formula :-

→ Force = m × a

→ F = 1500 × (-1.7)

→ F = -2550

Hence, the force required to stop the vehicle = -2550 N

( negative sign indicates that the direction of force is opossite to that of acceleration )

Answer 2

Answer:

mass of vechile=1500kg

stopped=2

acceleration =1.7 m

Explanation:

m.o.v=1500÷2

m.o.v.=140

acceleration
