step:1

Given data

mass m=75 kg

time t=2 min

step:2

use the kinematices to find the velocity driver

=>v-u=gt

=>v=9.8*2*60=1176 m/s

the velocity of driver falls v=1176 m/s

step:3

now we find the momentum

momentum P=mv=75*1176=88200 kg.m/s

SOLUTION :


Velocity of the driver 2 minute after jumping, v :

= g * (2 *60)

= 9.8 * 120

= 1176 m/s 


So, momentum acquired by the driver at the instant

= m * v

= 75 * 1176

= 88200 kg - m / s.  (ANSWER).

    When sky divers initially fall from an airplane their velocity v in miles per hour after free falling d feet can be approximated by v=60/11√d. (Because of air resistance, they will eventually reach terminal velocity.) How far do sky divers need to fall to attain a velocity of 55 miles per hour? (This value for d represents the minimum distance.)A sky diver needs to fall about ? feet to attain a velocity of 55mph.
