Question

calculate the force required to impart to a car availability of 30 metre per second in 10 second starting from rest mass 30​

Answer 1

Answer:

means here it is 30 / 10 = 3. The formula for finding the force is acceleration x mass, i.e. 1500 x 3 = 4500 Newton.

Answer 2

Answer:

Explanation:

Complete Question,

Calculate the force required to impart to a car a velocity of 30 m/s in 10 seconds starting from rest. The mass of the car is 1500 kg.

Solution,

Here, we have

Initial velocity, u = 0 (As starts from rest)

Final velocity, v = 30 m/s

Time taken, t = 10 seconds

To Find,

Force acquired,

At 1st we will find acceleration, a

we know that,

a = v - u/t

⇒ a = 30 - 0/10

⇒ a = 30/10

⇒ a = 3 m/s²

Now, we will find force acquired, f

we know that,

Force = mass × acceleration

⇒ Force = 1500 × 3

⇒ Force = 4500 Newtons

Hence, the force required to impart to a car is 4500 Newtons.
