A 1.50kg physics cart is initially traveling 2.80m/s when it collides with an ideal spring (with a spring constant of 730N/m) and natural length shown. The final time is defined as when the spring at maximum compression and the cart is about to rebound backwards. Neglect loss. Fill out the chart
How much did the spring's length change during the compression?
What is the length of the spring at maximum compression?
What is the spring force at this time?

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?
