Answer:
تكون دائمًا متعامدة مع سرعة الجسم وتكون دائمًا في اتجاه مركز انحناء المسار
Explanation:
Answer:
P = 1333.33 N
Explanation:
The pressure exerted by the boy on the floor can be calculated by the following equation:

where,
P = Pressure exerted by the boy = ?
F = Force Applied = Weight of Boy = 40 kg = 40 N (since 1 kg = 1N)
A = Area of application of force = 2(Area of one show) = 2(6 cm x 25 cm)
A = 2(0.06 m x 0.25 m) = 0.03 m²
Therefore,

<u>P = 1333.33 N</u>
Go with the last one because you need potential energy for kinetic energy
Answer: *360 mph*
Explanation:
I am pretty sure that it is 360 mph
3 times 120 = 360
Momentum = (mass) x (speed)
= (0.4 kg) x (45 m/s)
= 18 kg-m/s in the direction from the mound to the plate.
