Question

ATTENTION PLEASE ANSWER PLEASE TOMORROW EXAM​

Answer 1

By using third kinematical eqn

Vsq

Answer 2

initial velocity = 10m/s

acceleration a = 5m/s square

distance travelled = 30 m

final velocity v =?

v square - u square = 2aS

v square - 100 = 2*5*30

v square = 300 + 100

v square = 400

Taking square root both sides, we get

v = 20m/s
