At t = 0, a car registers at 30 miles/hr. Forty seconds later, the car’s velocity is now at 50 miles/hr. Assuming constant acceleration, find the value of this acceleration. Select one:
a. 20 miles/hr2
b. 0.5 miles/hr2
c. 0.5 miles/s2
d. 1.38 x 10-4 miles/s2
e. None of the given choices.

there was no answer choices but i think its representative

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
