User: In order for an object to accelerate, must be applied.

User: A ball is rolling down a hill. At one point near the top of the hill, its velocity is 2 m/s. Further down the hill, its velocity is 9 m/s. What is ?v? 9 m/s 7 m/s -7m/s -7m/s2

Weegy: The answer is 7 m/s

Question
A child kicks a soccer ball across the ground. The ball travels 10.0 meters in 0.56 seconds. What is the speed of the ball? 5.6 m/s 1.79 m/s 17.9 m/s 0.056 m/s User: Danny sails a boat downstream. The wind pushes the boat along at 21 km/hr. The current runs downstream at 15 km/hr. What is the actual velocity of the boat? 6.0 km/hr, downstream 1.4 km/hr, downstream 310 km/hr, downstream 36 km/hr, downstream
Weegy: 36 km/hr The velocity vectors are going in the same direction, so you can add them. User: Danny lowers the sails on his boat. He paddles upstream at 19 km/hr. The current is still running downstream at 15 km/hr. What is the actual velocity of the boat? 34 km/hr, downstream 34 km/hr, upstream 4 km/hr, downstream 4 km/hr, upstream Weegy: 34 km/hr, upstream User: Jesse travels 3.0 meters east and then turns and travels 4.0 meters north. What distance did Jesse travel? 1 m 5 m, northeast 7 m 7 m, northeast Weegy: The distance Jesse traveled is 7 m. His displacement however is 5 m. (More)
Question
What is speed? rate of motion rate and direction of motion the direction of motion the force of motion User: Jamal is skating on a sidewalk. His initial velocity is 0.0 m/s; 35 seconds later his velocity is 5.0 m/s. What is his acceleration? 7 m/s -7 m/s 0.14 m/s/s -0.14 m/s/s
Weegy: 0.14 m/s/s User: A car's acceleration is negative. This means the car is _____. slowing down speeding up changing direction traveling in a circle Weegy: a.slowing down User: A rocket's acceleration is 6.0 m/s2. Assuming it starts at 0 m/s, how long will it take for the rocket to reach a velocity of 42 m/s? 250 s 0.14 s 7.0 s 290 s Weegy: 7 seconds. 42/7 User: A ride at an amusement park moves the riders in a circle at a rate of 6.0 m/s. The radius of the ride is 9.0 meters. Which of the following shows the direction of the acceleration of the riders? a b c d Weegy: k / Discussion question B. An artist's conception of a rotating space colony in the form of a giant wheel. [ A person living in this noninertial frame of reference has an illusion of a force pulling her outward, toward the deck, for the same reason that a person in the pickup truck has the illusion of a force pulling the bowling ball. By adjusting the speed of rotation, the designers can make an acceleration |v|2/r equal to the usual acceleration of gravity on earth. On earth, your acceleration standing on the ground is zero, and a falling rock heads for your feet with an acceleration of 9.8 m/s2 . A person standing on the deck of the space colony has an upward acceleration of 9.8 m/s2 , and when she lets go of a rock, her feet head up at the nonaccelerating rock. To her, it seems the same as true gravity. ] (More)
Question
A ride at an amusement park moves the riders in a circle at a rate of 6.0 m/s. If the radius of the ride is 9.0 meters, what is the acceleration of the ride? 4.0 m/s2 0.67 m/s2 0.075 m/s2 54 m/s2
Weegy: Formula a = v^2 / r Here v = 6, r = 9, so a = 6^2 / 9 = 36/0 = 4. Hence 4.0 m/s2 (More)
