Once you land on mars, you get in your rover to begin exploring the surface. your rover accelerates at a pace of 3.5 km/hr/second for 10 seconds. what is the velocity of your rover after 10 seconds?

v=35 km/hr

Explanation:

From Newton law extension we get

a = (v - u) / t  

Where v = final velocity

u  = initial velocity

t  = time

a = acceleration

Newton's Law of dynamics they apply in space and other planets as well as on Earth.  

as given from data

Acceleration = 3.5 km/hr sec

Time = 10 sec.

U = 0 km per hr as assumed the object  is in rest condition  or start from rest

V = To be found?

so

a=(v-u)/t

put the values  we get

3.5 km/hr sec = (v km/hr - 0 km/hr) / 10 sec

3.5 km/hr sec × 10 sec = v km/hr

35 km/hr = v

v=35 km/hr

a and b sometimes have a positive value
