Question

. A block on a frictionless, horizontal table has a sum of external forces in the horizontal and vertical of zero (in both dimensions). We know it:

a. Is not moving
b. Is moving in a straight line at a constant speed
c. Is accelerating
d. Is not changing its velocity

Answer 1

U know
F=ma

Answer 2

If
F=0, then a=0

Answer 3

So no force , no acceleration

Answer 4

No acceleration means , no volocity change

Answer 5

Response plz!!! I can show it in a mathematical way

Answer 6

ok so its either moving in a straight line at constant speed or not moving at all

Answer 7

?

Answer 8

Ya right

Answer 9

d

Answer 10

but couldnt is also be A or B beacuse acceleration is constant?
