Question

An alien spaceship is 500mabove the ground and moving at a constant velocity 150m/S2 upwards.how high above the ground is the ship after 5seconds.

Answer 1

ExPlanation:

From question, the alien ship is moving with constant velocity right? then obviously it would not be accelerating. so, after every specific interval its height from ground will be increasing uniformly.. hmm getting the situation now?

So, After after t time its height will increase by 500m itself.

I can write it as; 150×t + 500

• And what have we got from our question that time 5 seconds, just put it there

= 150 × 5 + 500

= 750 + 500

= 1250 m

That was trouble-free! :P
