The direction of an object's velocity changes uniformly from east to south. What is the direction of the acceleration? Explain why
if The direction of an object's velocity changes uniformly from east to south. then the direction of the acceleration will also be east to west. Because direction of acceleration is same as direction of change in velocity.
Since, Acceleration is rate of change of velocity.

D Question 8 1 pts An object's velocity in the positive x-direction changes from 2.5 m/s to 8.7 m/s in 3.6 s A force of constant magnitude 18 N is acting on it. What is the object's mass in kg? Enter a number with two digits behind the decimal point.
An object's velocity changes at a constant rate from 2.0 m/s to 8.0 m/s in 5.0 s. The area underneath the acceleration vs. time graph for this object is
1. The velocity of an object traveling along the x-axis changes from 20 m/s to 60 m/s in 10 seconds. What was the displacement that occurred during this time? 2. An object moving along the x-axis initially has a velocity of 60 m/s and is slowing rest? down at the rate of 4 m/s per second. How far (in meters) will it travel before coming to 3. An accelerating object travels 12 meters from rest in a certain time. How...
Starting from one oasis, a camel walks 25.0 km in a direction 40˚ south of east, then walks 35.0 km due east, and then 50.0 km in a direction 20˚ west of north to a second oasis. What distance and in what direction must the camel walk straight back from the second to the first oasis? [Include a vector diagram
A woman walks 2.80 km south and then 2.50 km east, all in 2.60 hours. (a) What is the magnitude (in km) and direction (in degrees south of east) of hlat displacement during the given time? magnitude km direction O south of east (b) What is the magnitude (in km/h) and direction (in degrees south of east) of her average velocity during the given time? magnitude km/h direction south of east (c) What was her average speed (in km/h) during...
At one instant a bicyclist is 40.0m due east of a park's flagpole, going due south with a speed of 10.0m/s. Then 30.0s later, the cyclist is 40.0m due north of the flagpole, going due east with a speed of 10.0 m/s. For the cyclist in the 30.0s interval, what are the (a) magnitude and (b) direction of the displacement, the (c) magnitude and(d) direction of the average velocity and the (e) magnitude and (f) direction of the average acceleration?
A plane leaves Seattle, flies 85 miles at 30° north of east, and then changes direction to 45° south of east. After flying 115 miles in this new direction, the pilot must make an emergency landing in a field. The Seattle airport dispatches a rescue crew. In what direction and how far should the crew fly to go directly to the field? a) b) Check your answer with a careful graphical sum.
a 1.5 m long wire is pointing in a direction from north-east to south-west. A current of 650 ma is carried by the wire towards the south-west. the earth's magnetic field points due north with a strength of 0.45x10^-4 T. What force does the earth's magnetic field exert on the wire?
