1)
S₁ = V₁*t = 75*1,7 = 127,5 km
2)
S₂ = V₂*t = 91*1,7 = 154,7 km
Answer:
option D
Explanation:
given,
coefficient of friction between wall and tire = µ
speed of motorcycle = s
friction force = f = μ N
where normal force will be equal to centripetal force

for motorcycle to not to slip weight should equal to the centripetal force
now,


where "rg" is constant


Hence, the correct answer is option D
A) <span>Ivan does work when he lifts the basket
B) Work = Force * displacement
W = 20 * 2
W = 40 Joules
So, The Amount of work he does is 40 Joules
