Answer:

ForceonblockF=μmg+ma=0.2×1500g+1500×1=450g

Force on horse F=500a+μ×500g=150g

Totalforce=150+450=600kg−wt

A batsman scored 110 runs which include 7 boundaries and 7 sixes. What percentage of his total score did he make by running between the wickets?​

Answer :

36.36%

Step-by-step explanation:

no. of runs he made by boundaries : (7×4) = 28 runs

no. of runs he made by sixes : (7×6) = 42 runs

then, no of runs he made by running between the wickets = 110 - (42+28)

= 110 - 70

= 40 runs

So the percentage of runs he made by running between the wickets = (40/110) × 100

= 36.36%
