Question

sapling leaming this question was written by Sean Cordry at Walters State Community College Coyote (mc 16.0 kg) is about to try out his new rocket sled invention (m, = 50.0 kg), which can produce a thrust of 1600 N. Answer the three questions below Part A: What is the normal force (FN) exerted upwards by the road? Number FNIL Part If the effective frictional coefficient between the rolling wheels and the road is :00500 what is the value of the frictional force (1)? Number Part C: What will be the value of the acceleration (a) while Coyote and the apparatus are in motion with the rocket firing? Previous Next Save And Exit

Explanation / Answer

A)

total normal force = (16+50)*9.8 = 646.8 N ...............answer

B)

frictional force = 646.8 * 0.05 =32.34 N

C)

F = ma

1600-32.34= (16+50)*a

a = 23.75 m/s^2
