Use newton's second law: net force = m*a
in this case, m is 20kg and a is g. The net Force would be 196 Newtons
Answer:
B. Remains constant throughout the flight
Explanation:
If we completely neglect air resistance then the projectile will not have any horizontal resistances to deal with, therefore the horizontal component will remain constant throughout the flight. This would continue to be the case until it meets some form of resistance. Which assuming that everything else is normal would be the case since the force of gravity will push the projectile down (vertical component) until it hits the ground which in that instance would act as an opposing force to the horizontal component as well.
a friction force 10 N less than the applied force, a normal force equal to the gravtiational force
Answer:
Heat is transfered via solid material (conduction), liquids and gases (convection), and electromagnetical waves (radiation).

Answer:
3.61 m/s²
Explanation:
Given:
v = 12 m/s
x = 7 m
x₀ = 0 m
t = 6 s
Find:
a
x = x₀ + vt - ½ at²
7 m = 0 m + (12 m/s) (6 s) - ½ a (6 s)²
a = 3.61 m/s²
