Question

A force of 300N applied to a mass produced acceleration of 5 ms find velocity at end of 10 s

Answer 1

Answer:

correct your question please the unit of acceleration is m/s^2

Explanation:

Answer 2

The velocity at the end of 10 seconds is 50 m/s.

Given,

Force applied to the mass=300N

Acceleration produced by the mass=5 $m/s^{2}$.

To find,

the velocity at the end of 10 seconds.

Solution:

• The concept that is used here belongs to the chapter "Motion in a straight line".
• There are three equations of motion that are used in such questions:
• $v=u+at$.
• $s=ut+\frac{1}{2}at^{2}$.
• $v^{2} =u^{2} +2as$.
• where, u-initial velocity, v-final velocity, a -acceleration and s-displacement.
• As there is no mention of initial velocity here, we will assume it to be 0.

The velocity, v at the end of 10 seconds will be:

$v=u+at\\v=0+5X10\\v=0+50\\v= 50m/s.$

Hence, the velocity is 50 m/s.
