![PROBLEM 2
A car is travelling at a speed of 8m/s when the brakes are suddenly applied,
causing a constant deceleration 1m/s?. Determine the time required to stop the car
and the distance travelled before stopping.
PROBLEM 3
A car travels at a constant speed of 10 m/s, then decelerates at a constant 2
m/s until rest. Determine time elapsed and car's distance before rest.
PROBLEM 4
A car moves at 95 km/h past a police car that stops by the side of the road. One
minute later, the police car chases at 0.9 m/s?. How far the police car reaches the car?
PROBLEM 5
A stone is thrown with a speed of 25m/s at an angle of 40 deg above the
horizontal directly toward a very high concrete fence. The fence is 22 m from the
release point of the stone.
a. How long does the stone take to reach the fence;
b. How far above the release point does the stone hit the fence;
c. What are the horizontal and vertical components of stone's velocity as it hits
the fence;
d. When it hits, has it passed the highest point on its trajectory?
PROBLEM 6.
A heavy block weighing 300N is moved at a constant speed by a force
of 45N applied parallel to the motion.
a. What is the coefficient of friction involved in the problem?
b. What is the mass of the block?
C. Assuming the coefficient of friction is 0, find the acceleration of the block.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0c5cc403-a30e-4ec1-a8b8-ff144ee4e34d%2F685d242e-79cc-43ae-9b8c-77aa5502c46e%2Foddxuf_processed.png&w=3840&q=75)
