Step 1
Concept:
As we know, If an object is moving in a circle of radius r with constant speed v, then the motion is said to be a uniform circular motion. It has a radial acceleration aR that is directed radially toward the center of the circle which is called radial acceleration which is given by
aR=v2r
The velocity vector and the acceleration vector aR are continually changing in direction, but are perpendicular to each other at each moment. When the speed of circular motion is not constant, the acceleration has two components, tangential as well as centipental. As we know Newtons

Explanation:
The period of the satellite can be determined by;
T=4π2r2GM
where: T is the period, r is the radius of the orbit, G is the gravitation constant and M is the mass of the Earth.
Given that: r=6×(6.38×106)=38.28×106m,M=5.98×1024kg,G=6.673×1011Nm2kg2
Therefore, T=4(227)2(38.28106)26.67310115.981024
=5.7910163.991014
=145.113
=12.0463
T=12.05s
The period of the satellite is 12.05s

In Figure, a stationary block explodes into two pieces and R that slide across a frictionless floor and then into regions with friction, where they stop. Piece L, with a mass of 2.6 kg, encounters a coefficient of kinetic friction μL=0.40 and slides to a stop in distance deal = 0.15 m. Piece R encounters a coefficient of kinetic friction μR=0.50 and slides to a stop in distanced R=0.30 m. What was the mass of the original block?

Hi I need help with thisquestion. A uniform metal rod, with a mass of 3.1 kg and a length of 1.2 m,is attached to a wall by a hinge at the base. A horizontalwire bolted to the wall 0.51 m above the base of the rod holds therod at an angle of 25 degrees above the horizontal. The wireis attached to the top of the rod. (a) Find the tension inthe wire. (b) Find the horizontal and verticalcomponents of the force exerted on the rod by the hinge. Thank you
