Question

A BASE jumper runs off a cliff with a speed of Which of the following is closest to his speed after 0.5 seconds?
A) 10 m/s
B) 8 m/s
C) 6 m/s
D) 3 m/s
E) not given

Answer 1

Answer:

8m/s

Explanation:

The question is incomplete.

But if the given speed is 3m/s

t= 0.5s

From Newton's equation of motion v=u+at

U= 3m/s

V= 3+ 0.5×10 a=10m/s^2

v= 8m/s
