Assume that block a which has a mass of 30kg is being pushed to the left with a force of 75n along a frctionless surface. what is the friction for of block a on block b if thw block b has a mass of 24 kg and is accelerating at 0.50m/s2 to the right relaitve to the block a?
weight
normal force of the ground, weight
friction of the road, the normal force of the ground, force of the ground against the wheels pushing the car forward, weight

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
