Answer: 2 seconds
Explanation:
We can solve the problem by using the following SUVAT equation:
[tex]S=\frac{1}{2}(u+v)t[/tex]
where
S = 60 m is the distance covered
u = 10 m/s is the initial velocity
v = 50 m/s is the final velocity
t is the time taken
Re-arranging the formula and using the numbers above, we find the time taken:
[tex]t=\frac{2S}{u+v}=\frac{2\cdot 60 m}{10 m/s + 50 m/s}=2 s[/tex]
