Physics 1: Kinematics
A car accelerates at 3 m/s from rest for 10 s. How far does it travel?
A car is moving at 100 km/h. It stops in 5.0 s. What is the car's acceleration?
A ball is thrown off a building. If the ball is thrown up at 5 m/s and lands 3 seconds later
Find the height of the building
Find the impact velocity of the ball
An object is projected straight upward from the ground level with a velocity of 50 m/s. Ignoring air resistance, it will return to the ground in approximately how many seconds?
A swimmer can swim with a velocity of 1.0 m/s in still water. The swimmer wishes to swim directly across a river with a current of 0.50 m/s directed from upstream to downstream. To end up directly across the river the swimmer must head at what angle?
A river is 300 m wide and the water flows downstream, exactly south, at 4 m/s. If a swimmer, moving at exactly 6 m/s, attempts to swim across the river:
At what direction should the swimmer orient himself to swim straight across the river in the east direction?
How long will it take the swimmer to across the river?
On a good dry road, a car with good tires may be able to brake with a constant deceleration of 4.92 m/s . How long does such a car initially traveling at 24.6 m/s take to stop? How far does it travel this time?
A bullet was shot perfectly horizontally and was aimed directly at the center of a bulls eye 50 meters away. Suppose it struck 5 cm below the target. How fast was it going when it is fired?
A plastic ball is thrown with a velocity of 18 m/s stays in the air for 3.0 s.
At what angle with respect to the horizontal was it released?
What was the maximum height achieved by the ball?
