Question

A 1.50 m -long, 450 g rope pulls a 10.0 kg block of ice across a horizontal, frictionless surface. The block accelerates at 2.50 m/s^2. How much force pulls forward on the ice, the rope? Express your answer with the appropriate units. Express your answer with the appropriate units. F = 5.2 N force pushing two gliders along an air track. The 250 g spring between the gliders is compressed. Assume the force F acts and the whole system moves in the same direction. The spring does not sag. How much force does the spring exert on glider A? Express your answer to two significant figures and include the appropriate units How much force does the spring exert on glider B? Express your answer to two significant figures and include the appropriate units

Explanation / Answer

here,

length of rod , l = 1.5 m

mass of rope , mr = 0.45 kg

mass of block , m = 10 kg

accelration of the block , ab = 2.5 m/s^2

(a)

force pulls on the ice , F = mb * ab

F = 10 * 2.5

F = 25 N

the force that pulls the ice is 25 N

(b)

force that pulls the rope , F = ab * ( m + mb)

F = 2.5 * ( 10 + 0.45)

F = 26.13 N

the force that pulls forward on rope is 26.13 N
