1. You give a shopping cart a shove down an aisle. The cart is full of groceries and has a mass of 108 kg. The cart accelerates at a rate of 12 m/s2. How much force did you exert on the cart?

Question was not very clear if there are specific answer choices tell me and i'll try to you more. hope this though2 laps is 1 min. we know that for each min she does two times the amount of laps. for 12 laps we can do 12/2 which does give us 12 laps in 6 mins not 16 mins.

Rain is pulled by gravity which is a non contact force

Pe = 1/2k(x)^2  and .05n/m = .05x10^-9m = x
