Question

if a force of 15N acts upon a mass of 10 kg what is the velocity does it generate in 10 sec​

Answer 1

Explanation:

15=10×a

a=15/10

=1.5m/s

1.5×10

=15m/s

Answer 2

Answer:

15 m/s

Explanation:

Using Newton's second law of motion, set force is nothing but a product of mass and acceleration.

✰ F = ma

Where,

• F = Force
• m = mass
• a = acceleration

Here,

• F = 15 N
• m = 10 kg
• a = ? ( we need to find )

Substituting the values, we get:

• 15 = 10 × a
• a = 15/10
• a = 1.5 m/s²

then,

Using first equation of motion,

✰ v = u + at

Where,

• v is the final velocity of a body.
• u is the initial velocity of a body.
• a is the acceleration of a body.
• t is the time taken by a body.

Here,

• v = ? ( we need to find )
• u = 0 m/s
• a = 1.5 m/s²
• t = 10 s

Substituting the values in the equation, we get:

• v = 0 + 1.5 × 10
• v = 0 + 15
• v = 15 m/s

∴ The velocity generated by the force in 10 sec = 15 m/s
