What is happening in this graph from point B to C?

John walks 5 km east, and then turns around and walks 8 km west. What is John's displacement?

The diagram shows the velocity-time graph of an object. Which acceleration-time graph represents the same motion as the object?

A golf ball accelerates off a tee at 15 m/s², changing its velocity from 0 m/s to 50 m/s down the fairway.

How long did it take the golf ball to accelerate?

A car accelerates uniformly from rest at 3.2 m/s².

When the car has traveled a distance of 40 m, its speed will be

On a runway, an airplane is moving at constant acceleration for 1500 m.

If it starts from rest and becomes airborne after 10 s, determine its speed during take-off.

On a dry road, a car with good tires may be able to brake with a constant deceleration of 4.92 m/s².

How long does such a car initially travelling at 27.2 m/s take to stop?

A car increase its forward velocity uniformly from 45 m/s to 83 m/s while travelling a distance of 200 m. What is its acceleration during this time?

What is the horizontal acceleration of a projectile?

What is the vertical acceleration of a projectile?

A ball is thrown and follows the parabolic path shown above. Air friction is negligible. Point Q is the highest point on the path. Points P and R are the same height above the ground. How do the speeds of the ball at the three points compare?

At what point is v_x = 0 m/s?

As an object travels through the air, its vertical velocity 

At the instant, a ball is thrown horizontally with an initial velocity, another ball held at the same height is released from rest and drops to the ground. If we ignore air resistance, which ball hits the ground first?

Two objects of the same mass are launched from the ground. Object A has a launch angle of 45, while Object B has a launch angle of 65. Which object has the greatest maximum height?

Two objects of the same mass are launched from the ground. Object A has a launch angle of 45, while Object B has a launch angle of 65. Which object will fly the farthest?

u = 10 m/s  

In horizontal projectile motion, if the value of its initial velocity is as above, what is the value of its x-component and y-component?

A skateboarder rolls off a bridge into the river as shown.

If the skateboarder was originally moving at 7.0 m/s, how much time did the skateboarder spend in the air?

A baseball is thrown at a 22.5° angle and an initial velocity of 65 m/s. Assume no air resistance.

How far did the ball travel horizontally when it hit the ground?

An apple is thrown at an angle of 30° above the horizontal from the top of a building 20 m high. Its initial speed is 40 m/s.

The time taken for the apple to strikes the ground will be..

An object is projected with an initial velocity of 25 m/s and at an angle of 30° to the horizontal from the top of a cliff 65 m high.

Determine the maximum height reached by the object.

Valerie is standing on a ladder picking apples in her grandfather's orchard. As she pulls each apple off the tree, she tosses it into a basket that sits on the ground 3.0 m below at a horizontal distance of 2.0 m from Valerie. How fast must Valerie throw the apples (horizontally) in order for them to land in the basket?
