Momentum help
;D
Sorry if I sound very stupid...
A golfer hits a golf ball of mass 51g and the ball leaves the club with a velocity of 80m/s. Assuming that the ball and club are in contact for 0.0006s, find the ball's final momentum and the average force exerted by the club on the ball
Next :
diver dive from a height of 36m into the sea. Mass = 61kg.
In a free-fall, before parachute is opened, diver reach terminal speed of 90m/s.
Calculate force of air resistance on the diver when terminal speed
:-[
________________ B
/ A

Velocity vs time graph
A overtakes b t=0
B accelerates and overtakes A
What is the maximum distance between the cars before B catches up with A
Why is it that part of the graph, (with dots)
where both lines intersect
I don't understand... can someone please explain??
AHHH! Thank you
:'(
