Answer:
8 kg*m/s and 2m/s
Explanation:
momentum is mass times velocity. since the velocity changes by 2 m/s. you just take the difference from final velocity to beginning velocity.
4kg*12m/s = 48 kg*m/s
4kg*10m/s = 40 kg*m/s
48kg*m/s - 40 kg*m/s = 8kg*m/s
We Know, F = m*a
Here, F = 34 N
m = 213 Kg
Substitute their values in the equation,
34 = 213 * a
a = 34/213
a = 0.159 m/s²
So, your final answer & the acceleration of the object would be 0.159 m/s²
Hope this helps!
Oil is less dense than water or most liquids found in Saldana dressing, so the denser liquid sinks to the bottom, leaving the oil on top. It's same principle on how a helium balloon floats in air, the helium is less density than the air around it.
