Two people are paddling a canoe downstream with a speed of 3.5 km/h relative to the river. If the river is flowing at 22 km/h, how long will it take
them to reach the canoe dock 25 km away?
A. 1.0 h
B. 1.4 h
C. 1.6 h
O
D. 1.2 h

a person with a mass of 106kg has a weight of 1060n

pretty sure it's false

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
