Question

In order to move

a 10kg object from
constant force of 4N is applied
for 4 minutes Calculate the velocity of
object at the end of 4 minutes.​

Answer 1

Answer:

v = 400 m/s

Step-by-step explanation:

To find - v (final velocity)

Given :-

• Mass of object - 10 kg
• Constant force applied - 4 N

= 4 kgm/s²

• Force applied for - 4 min

= 240 s

Now,

F = ma

a = F/m

= 4 kgm/s² / 10 kg

= 2/5 m/s²

We can find 'v' by using 1st eq. of motion,

v = u + at

Initial velocity (u) = 0 m/s

Therefore,

v = 0 + (5/3 m/s²) × (240 s)

v = 400 m/s
