Question

an object starts from rest and accelerates uniformly in a straight line in the positive x direction. after 11 seconds, its speed is 70.0 m/s. a) determine the acceleration of the object. b) how far does the object travel during the first 11 seconds? c) what is the average velocity of the object during the first 11 seconds?

Answer 1

a. 70

b. 770

c. 770

Step-by-step explanation:

a.change in velocity/time

770÷11

=70

b.70×11

770

c. Displacement/time

x/11s=70

c.m

x=70×11

=770m/s
