have fewer economic restrictions
Explanation:
A 50 kg
490N = m(kg) *9.8(m/s^2)=>m=490/9.8 = 50kg
Answer:
8.2 m/s²
Explanation:
m = mass of the block
μ = Coefficient of kinetic friction = 0.17
= Normal force on the block by the ramp
= kinetic frictional force
Force equation perpendicular to ramp surface is given as

Kinetic frictional force is given as


Force equation parallel to ramp surface is given as




m/s²
About 1.3 SECONDS.............
Answer:
G
Explanation
The acceleration of gravity is constant, and = 9.8 m/s² , no matter what mass of the object is. Initial speed for both objects = 0 m/s. So, after 2 sec the objects will have the same speed and the same distance.
Answer G: speed=v, distance =d.
