Car is traveling at a speed, what speed will a truck have the same momentum?

AI Thread Summary
A car with a mass of 964.0 kg traveling at 63.3 km/hr has a momentum of 16,947.12 kg·m/s. To find the speed at which a truck weighing 3,530.7 kg would have the same momentum, the equation p = mv is used. Solving for the truck's speed yields approximately 4.79 m/s. This speed converts to about 17.25 km/hr. Thus, the truck must travel at 17.25 km/hr to match the car's momentum.

A car with a mass of 964.0 kg is traveling at a speed of 63.3 km/hr. At what speed (in km/hr) will a 3530.7 kg truck have the same amount of momentum as the car?

First start by asking yourself what is the definition of linear momentum and hence what is the momentum of the car?
 
car
speed=63.3km/hr=17.58m/s
p=964*17.58
p=16947.12

truck
p=mv
16947.12=3530.7*V
V=4.79m/s??

Yes, that should be correct.
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'Minimum mass of a block'
Here we know that if block B is going to move up or just be at the verge of moving up ##Mg \sin \theta ## will act downwards and maximum static friction will act downwards ## \mu Mg \cos \theta ## Now what im confused by is how will we know " how quickly" block B reaches its maximum static friction value without any numbers, the suggested solution says that when block A is at its maximum extension, then block B will start to move up but with a certain set of values couldn't block A reach...
