Question

A 4kg object is at rest. How much force is required to get the object to a velocity of 20m/s in 2 seconds? (Show work and include units)

Answer 1

Step-by-step explanation:

Answer:-

The Object was at rest. So, Initial Velocity is Zero.

• [Initial Velocity]u = 0
• [Final Velocity]v = 20 m/s
• [Time]t = 2 seconds
• Mass = 4kg
• Force = ?

We know that:-

`\sf{Force = Mass * ((v-u))/(t)}`

Applying it, we get:-

`\sf{Force = 4 * ((20-0))/(2)}`

`\sf{Force = 2 * ((20))/(2)}`

`\sf{Force = 2 * 10}`

`\sf{Force = 20 \ N \ (Newton)}`

Hope it helps :)
