Homework Statement The mass of the moon is 7.35 x 10^22 kg and its distance from the Earth is 3.84 x 10^5 km. Taking Earth's mass to be 5.98 x 10^24, calculate what Newton called "the force resquisite to keep the moon in her orb." mass of moon = 7.35 x 10^22 kg distance from earth= 3.84...

I see, so after adding 24+18 and dividing by 2, multply the time and that will be my distance ? Once done, do the same for the other 2 (but without finding the average acceleration) and add, thus giving my displacement?

so, bastically i do d = vt with the time and velocities, add them up and that's my displacement?

Ohh i see. If i were to add them, I would get the displacement correct? or should i use d = ut +\frac{1}{2} at^2 after adding.

How am i able to find the acceleration and v1 by using all of these variables (specifically time and velocity)? Would i use d = vt at all?

so do i do: 18 m/s x 5.0s then 24 x 4.0s then add them up? What do i do with the 6.0s and the uniform motion? When adding do i find the displacement?

Homework Statement A slight Earth tremor causes a large boulder to break free and start rolling down the mountainside with a constant acceleration of 5.2 m/s^2. What is the boulder's velocity after 5.0s. Homework Equations I used: v2 = v1 + a x Δt The Attempt at a Solution v1 = 0 [because...

Hi, I am new to the fourm. If it is not any touble, please help me with a kinematic problem. Homework Statement A car travels east along a straight road at a constant velocity of 18 m/s. After 5.0s, it accelerates uniformly for 4.0s, reaching a velocity of 24 m/s. For the next 6.0s, the car...
