- An object is at rest at #(6 ,2 ,8 )# and constantly accelerates at a rate of #1 m/s^2# as it moves to point B. If point B is at #(3 ,7 ,5 )#, how long will it take for the object to reach point B? Assume that all coordinates are in meters.
- A model rocket is shot straight upward with an initial velocity of 32 m/s. Its upward acceleration is a constant 6 m/s2. When the fuel is used up at a height of 75 m, what is its velocity?
- Physics question regarding acceleration of 2 boxes attached to pulley over inclined plane?
- An object is at rest at #(8 ,2 ,5 )# and constantly accelerates at a rate of #7/4 m/s^2# as it moves to point B. If point B is at #(2 ,3 ,7 )#, how long will it take for the object to reach point B? Assume that all coordinates are in meters.
- A car is moving in the east direction with the velocity of 30.0 miles/hour. To avoid head on collision the breaks are applied and the car is brought to rest in 10.0s. Calculate the average acceleration of the car?
- How does acceleration differ from force?
- What is the average speed of an object that is not moving at #t=0# and accelerates at a rate of #a(t) =4-t# on #t in [2,3]#?
- If an object with uniform acceleration (or deceleration) has a speed of #6 m/s# at #t=0# and moves a total of 4 m by #t=3#, what was the object's rate of acceleration?
- An object is at rest at #(2 ,8 ,6 )# and constantly accelerates at a rate of #5/3 m/s^2# as it moves to point B. If point B is at #(3 ,2 ,7 )#, how long will it take for the object to reach point B? Assume that all coordinates are in meters.
- An object is at rest at #(8 ,2 ,5 )# and constantly accelerates at a rate of #7/4 m/s^2# as it moves to point B. If point B is at #(6 ,5 ,1 )#, how long will it take for the object to reach point B? Assume that all coordinates are in meters.
