Answer:
Net force, F = 205.59 N
Explanation:
Given that,
Mass of a bobsled, m = 89 kg
Initial speed of the bobsled, u = 0
Distance travelled, d = 33.8 m
Final speed of the bobsled, v = 12.5 m/s
To find,
The magnitude of the net force
Solution,
Let a is the acceleration of the bobsled. Using the third equation of kinematics as :
[tex]v^2-u^2=2ad[/tex]
[tex](12.5)^2=2a\times 33.8[/tex]
[tex]a=2.31\ m/s^2[/tex]
Let F is the magnitude of net force acting on the bobsled. It can be calculated as :
[tex]F=ma[/tex]
[tex]F=89\ kg\times 2.31\ m/s^2[/tex]
F = 205.59 N
Therefore, the magnitude of the net force acting on the bobsled is 205.59 N.
