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?

Answer:

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

The velocity of the rover after 10 seconds given that it accelerates at a pace of 3.5 km/hr/second is 35 Km/hr

What is acceleration?

This is defined as the rate of change of velocity which time. It is expressed as

a = (v – u) / t

Where

  • a is the acceleration
  • v is the final velocity
  • u is the initial velocity
  • t is the time

How to determine the final velocity

  • Initial velocity (u) = 0 Km/hr
  • Time (t) = 10 s
  • Acceleration (a) = 3.5 Km/hr/second
  • Final velocity (v) = ?

a = (v – u) / t

3.5 = (v – 0) / 10

3.5 = v / 10

Cross multiply

v = 3.5 × 10

v = 35 Km/hr
