A powerful motorcycle can produce an acceleration of 3.50 m/s2 while traveling at 90.0 km/h. At that speed, the forces resisting

motion, including friction and air resistance, total 400.0 N. (Air resistance is analogous to air friction. It always opposes the motion of an object.) What is the magnitude of the force that motorcycle exerts backward on the ground to produce its acceleration if the mass of the motorcycle with rider is 245 kg?

Answer:

1257.5 N

Explanation:

a = acceleration of the motorcycle = 3.50 m/s²

f = force of resisting motion = 400.0 N

m = mass of motorcycle = 245 kg

F = magnitude of force that motorcycle exerts backward = ?

Magnitude of force that motorcycle exerts backward is given as

F = f + ma

Inserting the values

F = 400.0 + (245) (3.50)

F = 1257.5 N

What is 1113.28 in a sig fig?
Afina-wow [57]

Answer:

6 significant figure

Explanation:

The digits 111328 all are 6 figures with no figure being zero, neither zero after the other digits. In this case, all the numbers are significant and since they are only six numbers, then this is a six significant figure. In case we add another zero after digit 8, the zero is not significant but if added either infront of 8 or 2, the zero becomes significant.
