Record the values provided in the assignment and do the calculations. When two fields are provided for a quantity, the number part of the answer goes into the first field and the units in the second field. Example: How many centimeters in 1 meter: 100 cm Useful unit conversions to change data from English units of force, weight in pounds, and speed in MPH to metric units of force in Newtons, mass in kilograms, and speed in meters/ second: 1 pound = 4.448 Newtons 1 pound of weight requires 0.4536 kg of mass 1 MPH = 0.44704 m/s 1. Use the estimated thrust of a JATO rocket and the time it fires to predict the change in momentum of the car from the time the rocket starts until it stops. You can use the time given in the story or the shorter time listed in the properties of the 15-KS-1000 solid fuel rocket. Formula: Change in Momentum = Force x Time Rocket thrust = 4448.22162 N Time thrust applied = 15 S Impulse = 66720 N The car's change in momentum = 66720 N AP =FAt + F = 10001bf . . 4. 448N 11lbf 4448N AP = (4448N)(15s)= 66720 N . S Rocket Thrust in units of Newtons 4448 N Time thrust is applied 15 S Impulse 66720 N The car's change in momentum 66720 N
