if the unit of force is 10 Newton the unit of acceleration is 2 m/s2 square into velocity is 5 m/s then the unit of momentum is
(1) 10kgm/s
(2) 15 kgm/s
(3) 25kgm/s
(4) 30 kgm/s
f = m a ... p = m v
To find the unit of momentum, we need to understand its formula. Momentum is defined as the product of mass and velocity.
The formula for momentum is:
Momentum (p) = mass (m) x velocity (v)
The unit of force is given as Newton, which is represented by N. The unit of acceleration is given as m/s^2.
Since acceleration is the rate of change of velocity, we can calculate the change in velocity by multiplying acceleration by time. However, the time is not given in the question, so we cannot directly calculate the change in velocity.
However, we are given the velocity as 5 m/s. So we will assume that this is the final velocity. Since we do not have the initial velocity, we cannot calculate the change in velocity or the time.
Now let's consider the options provided:
(1) 10kgm/s
(2) 15 kgm/s
(3) 25kgm/s
(4) 30 kgm/s
We know that momentum is the product of mass and velocity, and the units are:
mass (kg) x velocity (m/s) = kgm/s
Looking at the options, we can see that none of them match the units for momentum. The units provided in the options are only in kgm/s, which is incorrect.
Based on the information given, we cannot calculate the exact unit of momentum. Therefore, the answer is none of the options provided.
