A student pushes a shopping cart filled with groceries. The cart has a mass of 12 kilograms (ko). The student pushes the cart with a force of 15 newtons (N). Assuming the ground is frictionless, how fast will the cart accelerate until the student stops applying the force? 0.625

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?
