An object has a position given by = [2.0 m + (5.00 m/s) t]

+ [3.0 m - (2.00 m/s²) t²]
, where quantities are in SI units. What is the speed of the object at time t = 2.00 s?

Question

An object has a position given by

= [2.0 m + (5.00 m/s) t]
An object has a position given by = [2.0 m + (5.00 m/s) t] + [3.0 m - (2.00 m/s2) t2] , where quantities are in SI units. What is the speed of the object at time t = 2.00 s? A) 6.40 m/s B) 9.43 m/s C) 7.00 m/s D) 7.65 m/s E) 13.0 m/s

+ [3.0 m - (2.00 m/s²) t²] An object has a position given by = [2.0 m + (5.00 m/s) t] + [3.0 m - (2.00 m/s2) t2] , where quantities are in SI units. What is the speed of the object at time t = 2.00 s? A) 6.40 m/s B) 9.43 m/s C) 7.00 m/s D) 7.65 m/s E) 13.0 m/s

, where quantities are in SI units. What is the speed of the object at time t = 2.00 s?
