Answer:

Uniform Circular Motion What is the direction of the force that acts on the clothes in the spin cycle of a washing machine?

Explanation:

The string acts as the centripetal force that pulls the bucket and water into the center and keeps them from following their paths of inertia, giving the illusion that centrifugal force is pulling the water away from the center. ... If you spin the bucket too slowly, the water will fall out and you will get wet.

An object is moving in a straight line at constant speed. A resultant torce begins to act upon

alekssr [168]

Answer: The velocity magnitude or the velocity direction chages.

Explanation:

According to Newton's second law of motion, the acceleration of a system moved in same direction and is also directly proportional to the external force which acts on it while inversely proportional to the mass. The formula is: a = F/m

Based on the question, since the object obtains acceleration, then it can be infered that there will be changes in the velocity magnitude or the direction as a result of the motion.

A car traveling at 50 m/s uniformly accelerates to 60 m/s over an 58 second interval. What is the displacement?

yawa3891 [41]

Explanation:

here u = 50m/s

v = 60m/s

t = 58 s

then a = (60-50)/58 m/s2

= 0.17m/s2

now s= ut+1/2at2

so , 50×58+0.5×0.17×(58)^2 m
