Well we can just use F=ma. The force is 10N, the mass is 50 kg, solve for a. Well since we kg and N, no conversion is necessary. So just plugging in the numbers, we get
10N = 50 kg · a
A newton is just
The s^2 and 50 kg you multiply
The kg's cancel and 10/50 is 1/5
So the acceleration is 1/5 m/s^2
<u>Answer: </u>
Cat has 2.02 seconds to right itself.
<u>Explanation: </u>
Initial height of cat from ground = 20 meter.
We have equation of motion , , s is the displacement, u is the initial velocity, a is the acceleration and t is the time.
In this the velocity of cat in vertical direction = 0 m/s, acceleration = acceleration due to gravity = 9.8 , we need to calculate time when s = 20 meter.
Substituting
So, cat has 2.02 seconds to right itself.
