1.

an artificial satellite is moving in a circular orbit of radius 42250 km. calculate its speed if it takes 24 hours to go around the earth

Answer» LET it's SPEED be V which will be constant (CIRCULAR motion).
Circumference of orbit is distance travelled by SATELLITE in 24 hours.
THEREFORE
V×24 = 2π42250
=> V = 2π42250/24 Km/he

Hope it will help.
