A block that is connected to a horizontal spring is allowed to oncillate, and a graph of te velocity as a function of time is shown in the figure. At = 7 s, the block detaches from the spring. All frictional forces are considered to be negligible. What distance will the block travel from t = 7 tot 10 s?
a.0.0 m
b.1.5 m
c.3.0 m
d10.0 m

Plss anybody know how to do this? ? i need the answers from a through d

Bob camina 200 m sur, luego trota 400 m suroeste, luego camina 200 m en una dirección 30? norte del este. a. dibuje una gráfica de los movimientos de bob. use una regla y transportador. b. use método gráfico y analíitico para hallar el desplazamiento total que bob recorrió. (magnitud y dirección) c. compare los resultados obtenidos por el método gráfico y analítico. (por ciento de diferencia).

An astronaut in space cannot use a scale or balance to weigh objects because there is no gravity. but she does have devices to measure distance and time accurately. she knows her own mass is 77.4 kg , but she is unsure of the mass of a large gas canister in the airless rocket. when this canister is approaching her at 3.50 m/s , she pushes against it, which slows it down to 1.30 m/s (but does not reverse it) and gives her a speed of 2.60 m/s . what is the mass of the canister?
