1.A car goes off a cliff horizontally at 49 m/s and falls for 5 seconds a. What us the vertical speed of the car after 5 seconds? b. What is the horizontally speed of the car after 5 seconds ? c. What is the actual speed of the car after 5 seconds ? 2.A golfer wants to drive a golf ball a distance of 120 m. If the 3-wood launches the ball at 12 degree above the horizontal. What must be the initial speed of the ball to achieve the required distance ? 3. A place kicker must kick a football from a point of 28 m from the goal and the ball must clear the crossbar, which is 3 m high. When kicked, the ball leaves the ground with a speed of 25 m/s at an angle of 45 degree to the horizontal. a. By how much does the ball clear of fall short of clearing the crossbar? b. Does the ball approach the crossbar while it still rising or falling ? 8. Flash throws a ball into the air as hard as he can and then runs as fast as he can under the ball in order to catch it. If his maximum speed in throwing the ball is 15 m/s and his best time for the 50 m distance is 5 seconds, how high does the ball raise and at what angle did he shoot i? If you answer all these questions, your the best :O !
Maisie drags a 1kg mass along a table with a Newton meter so that it accelerates at 0.25 m/s. The Newton-meter reads 0.4N, calculate the force of friction between the mass and the table

In preparation for an electrophoresis procedure, enzymes are added to DNA in order to 1.) Convert the DNA into gel 2.) Cut the DNA into fragments 3.) Change the color of the DNA or 4.) Produce longer sections of DNA
What is the method of adding crests and troughs of interfering waves together to describe a new wave?
a 5 kg block is pulled across a table by a horizontal force of 40 n with a frictional force 8 n opposing the motion. calculate the acceleration of the object
Donny is a wide reciever on the football team and he is practicing his routes. Coach keeps telling him that he needs to accelerate through the catch. Donny's precatch speed is 9 m/s and he is in the act of catching the ball for 1.1 seconds. Donny is capable of an accelerating at 2.6 m/s2. What is the final speed that Donny's coach should expect?
Is it possible for an object that has a constant negative acceleration to change the direction in which it is moving.
