Answer:
a) 17.086m
b) 0.1671 m
Explanation:
Given data: speed of water through the hose = 1.81 m/s
through the nozzle = 18.3 m/s
We know that maximum height of an object with upward velocity v is given by,
a) H = v^2/2g
where H is the maximum height water emerges
= 18.3^2/(2×9.8) = 17.086 m answer
b) Again,
H = v^2/2g
= 1.81^2/(2×9.8) = 0.1671 m
Answer:150N
Explanation:
Total mass=mass of skate board + mass of rider
Total mass(m)=46kg + 4kg
Total mass(m)=50kg
Acceleration(a)=3m/s^2
Force(f)=mass x acceleration
Force=50 x 3
Force=150N
Answer:
pulling force
Explanation:
because the person is pulling that cart.
