Answer:
No car will slide
Explanation:
Neither car will slide because proper bank does not required frictional forces. To prevent the car from traction through curve, a component of normal forces provides necessary centripetal forces. which prevent them to slide.
No car will slide since both car are going with the proper speed for given banking angle
Distance=SPEED*Time(Scalar)
Displacement=VELOCITY*Time(Vector)
Disp= (3m/s)(1.8s) =5.4m
Answer:
Newton's second law: F=ma.
Force = mass x acceleration
This basically means, that the more massive something is, and the faster it is going, the more force the object will have.
So, the factors that can be used to find acceleration are:
F=ma
a=F/m
So, we see that the correct answer is A, mass and force.
Let me know if this helps!
Answer:
a) Fg = m* g
b) Fg = 58.86 N
c) pointing down (towards the center of the Earth)
d) N = 58.86 N
e) pointing up
Explanation:
a) Force is defined as mass of the object times the acceleration it is subjected to. In our case, the block is subjected to the acceleration of gravity (g), therefore the force due to gravity (Fg) is Fg=m*g
b) perform the indicated product of part a):
Fg = m*g = 6 kg * 9.81 m/s^2 = 58.86 N
c) since the object is not moving, that means that the contact force exerted by the surface were the block is resting, must equal the acting force of gravity, but pointing in opposite direction, so the NET force on the block is zero. Therefore, the magnitude of the normal force (N) must equal the magnitude of the object's weight: N = 58.86 N
d) As explained in part c), the normal force must be acting in opposite direction to the force of gravity, which means pointing up.
