40 N. If you’re using F=MA MxA would be 10x4 which would get you 40 N
I’m not really sure but I think it’s D type 1 lever
Answer:
Electric switch is commonly known as the key of an electric circuit.
Free fall is a special case of motion with constant acceleration, because acceleration due to gravity is always constant and downward. For example, when a ball is thrown up in the air, the ball's velocity is initially upward.
#A
Mass=4.4kg
acceleration=-1.74m/s^2
Use newtons second law



#B
initial velocity=u
Final velocity=v=0
Acceleration=a=-1.74m/s^2
Time=t=1.27s
