Suppose we drop a 0.145-kg baseball and a 7.0-kg bowling ball simultaneously from rest. They both fall for 0.50 s and both reach the same speed of 4.9 m/s just before hitting the ground.

(a) What impulse (magnitude and direction) did each ball receive from the earth during the interval between being released and hitting the ground?

(b) What is the rate at which each ball received momentum as they dropped (assuming the rate is constant)?

(c) Is this rate consistent with equation C2.6 in each case?

i don’t know what the answer is i wish i

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
