Please help asap! a shopper pushes a 5.32 kg grocery cart with a 12.7 n force directed at -28.7 below horizontal. a friction force of 8.33 n pushes back against the motion. what is the acceleration of the cart? (in m/s^2)

Much of the information taught in earth-space science would not be available if it weren’t for our remote sensing abilities. explain two ways our remote sensing strategies contribute to our knowledge of these topics.

If anyonee has done the momentum lab practical in physics can you give me the answers i am s lostt rnn : (

Estimate the kinetic energy of mars with respect to the sun as the sum of two terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the sun. (assume mars is a uniform sphere with mass = 6.4×10 to the power of 23 kg, radius = 3.4×10 to the power of 6 m, rotation period = 24.7 hours, orbital period = 686 days and is 2.3×10 to the power of 8 km from the sun.)
