Question

Suppose a car is accelerating at a rate of 20 m /s
2
. If the net force is tripled and

the mass is doubled, then what is the new acceleration of the car

Answer 1

Answer :-

Given :-

• a = 20 m/s²
• Force = 3F ( force is tripled )
• Mass = 2M ( Mass is doubled )

To Find :-

• New acceleration

Solution :-

We know that,

Force = Mass × Acceleration

→ A = F/M

Let new acceleration be A'

Now, when the force is tripled and mass is doubled :-

→ 3F = 2M × Acceleration

→ A' = 3/2 F/M

→ A' = 3/2 A

→ A' = 3/2 × 20

→ A' = 30

New acceleration = 30 m/s²
