If the acceleration of an object is zero, then that object cannot be moving. True False

A race car travels around the horizontal circular track that has a radius of 310.6m, If the car increases its speed at a constant rate of 6.09 m/s^2 starting from rest, determine the time needed for it to reach an acceleration of 8.49 m/s^2.

A particle's velocity can have both magnitude (speed) and direction which vary as a function of time. A particle's velocity can have both magnitude (speed) and direction which vary as a function of time. True False

When applying the equations of kinematics for an object moving in one dimension, which of the following statements must be true?The velocity of the object must always be in the same direction as its acceleration. (Select all that apply)The acceleration of the object must remain constant.The velocity of the object must remain constant.The position of the object must increase with time.The velocity of the object must increase with time.

If the velocity of an object is zero at some point, then its acceleration must also be zero at that point. True False

A train is traveling south at 58.4 m/s when the brakes are applied. It slows down with constant acceleration to a speed of 6.00 m/s in a time of 9.00 s.   How far does the train travel during the 9.00 s? If the displacement is toward north, enter a positive value. If the displacement is toward south, enter a negative value. answer in m

A spider is walking to the left along a ruler which is being pulled to the right. The speed of the ruler is greater than the speed of the spider walking along the ruler. The speed of the spider with respect to the ground is   less than the speed of the ruler. The same as the speed of the ruler. zero. greater than the speed of the ruler.

A particle is initially moving along the positive x-axis at a speed of 8.10 m/s. After 2.15 s, the particle is moving along the negative y-axis at a speed of 4.67 m/s. Find the x and y components of the particle's acceleration. x component y component

average velocity and instantaneous velocity are always similar True False

Determine the displacement (change in position), Δx , of the object during the 5-second time interval.
