Answer:(a)0,(b)1.061 kg-m/s
Explanation:
Given
mass of ball is 0.10 kg
Initial speed is 15 m/s
Maximum height reached by ball is h
final velocity =0
thus momentum of ball at maximum height is 0 as velocity is zero
For halfway to maximum height
where
v=10.61 m/s
Thus its momentum is
Answer:
.He shouldn't eat:
1.Sugar
2.Fast food
3.Fat
Exercise:
1.Heel touches while lying on the ground
2.Abdominal crunches
3.V ups
3.Planks
P.E = m*g*d
where m is the mass of body , d the vertical distance & g is the gravity acceleration and it equals constant = 9.81 m/s^2
so ,, P.E = 2 * 3 * 9.81
P.E = 58.86 N.m
