Answer:
t = 0.5 seconds
Explanation:
Given that,
Mass of a body, m = 50 kg
Initial speed, u = 0
Final speed, v = 5 m/s
The resistance force of the ground = 500 N
We need to find the time of contact. The formula for the force acting on an object is given by :
F = ma
a is acceleration
[tex]F=\dfrac{m(v-u)}{t}\\\\t=\dfrac{m(v-u)}{F}\\\\t=\dfrac{50\times (5-0)}{500}\\\\t=0.5\ s[/tex]
So, the time of contact is 0.5 seconds.
