Question

the object has an initial speed of 50 metre per second and decelerates uniformly 0.5 metre per second square for 100 second
calculate the travel distance by the object from time = 0 to time = 100s

Answer 1

Explanation:

Initial velocity u=0 acceleration a=1ms−2

Time interval t = 4 seconds 

Distance travelled =s=ut+21at2

s=0×4+21×1×42

=0+21×1×16

=8m.
