There is no acceleration in vertical direction
Fn = mg + Fp sin 35
Frictional force = 99.7 N
Net force in forward direction = Fp cos 35 - 99.7
= 168 cos 35 - 99.7
= 37.91 N
net acceleration of chair = net force / mass
= 37.91 / 50
= .7582 m / s² .
If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A
the law of force show that focuses will always come in 2 or pairs and it also says that one body cannot exert a force on another without experiencing a force itself.
( hope that helps :) #pk1208 is here to help )
Maybe if you would slide on your stomach you can get out of there.
says that force equals mass times acceleration
That situation is described by Newton's Second Law of Motion. According to NASA, this law states, "Force is equal to the change in momentum per change in time. For a constant mass, force equals mass times acceleration.
The correct option is bat pushes on the ball with the same force as the ball pushes on the bat.Explanation:
According to Newton’s law action and reaction are equal in magnitude but opposite in direction so the same case will apply here. The bat pushes on the ball with the same force as the ball pushes on the bat just the direction is opposite.Answer to Q2
Mass will remain the sameExplanation:
The gravitational pull is related to the weight of objects. Weight is the force with which earth attracts everything towards its centre. And mass is the quantity of matter inside the body. So on the moon the quantity of matter inside a body does not change therefore the mass would remain the same.Answer to Q3
Force required is 16 NewtonExplanation:
Mass= 80 kg
Acceleration = a = 0.2
So F = ma
Putting the values
F= 80 x 0.2
F = 16 N
It implies that the sum of the forces was not 0 and the coin moved according to Newton's 2nd law.
