Can a generous soul help me on this? A block of mass m is slid down a rough inclined plane. At the bottom of the inclined plane the block runs into another 1-kg block and comes to rest. Which expression would give the energy transferred to the second block?
assume the height of the inclined plane to be h, its length to be d and fs represent the force of friction.

The position of a dragonfly that is flying parallel to the ground is given as a function of time by r⃗ =[2.90m+(0.0900m/s2)t2]i^− (0.0150m/s3)t3j^. a: at what value of t does the velocity vector of the insect make an angle of 34.0 degree clockwise from the x-axis? b: at the time calculated in part (a), what is the magnitude of the acceleration vector of the insect? c : at the time calculated in part (a), what is the direction of the acceleration vector of the insect?
