Question

calculate the force required to impact a car velocity of 50m/s in 25 second from the rest the weight of car is 1000 kg​

Answer 1

Given :

• Final velocity (v) = 50 m/s
• Initial velocity (u) = 0 m/s
• Time (t) = 25 seconds
• Mass (m) = 1000 kg

To find :

• Force (F)

According to the question,

At first we will find the acceleration using newtons first equation of motion then we will calculate force,

→ v = u + at

Where,

• v stands for Final velocity
• u stands for Initial velocity
• t stands for Time
• a stands for Acceleration

Substituting the value,

→ 50 = 0 + a(25)

→ 50 - 0 = 25a

→ 50 = 25a

→ 50 ÷ 25 = a

→ 2 = a

.°. The acceleration is 2 m/s²...

Now we will calculate force,

→ Force = Mass × Acceleration

Or,

→ F = ma

Substituting the values,

→ F = 1000 × 2

→ F = 2000 N

So,the force is 2000 N..
