Asatellite with mass 500 kg is placed in a circular orbit about earth (mass= 5.98 x 10^24 kg), radius = (6.4 x 10^6), a distance of 1500 km above the surface. (a) what is the force gravity acting on satellite? (b) what is the satellite’s acceleration? (c) what is the satellite’s orbital speed?

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 710 n/m. it is initially at rest on an inclined plane that is at an angle of θ = 23° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk = 0.19. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. a) what is the block's initial mechanical energy? b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.

The slope of a velocity time graph over any interval of time gives the during that interval

True or false graphs must include scales that increase by the same amount
