Your mass is 73.3 kg, and the sled s mass is 10.1 kg. You start at rest, and then you jump off the sled, after which the empty sled is traveling at a speed of 5.48 m/s. What will be your speed on the ice after jumping off?     0.38 m/s     1.22 m/s     0.99 m/s     0.76 m/s

In the process of being thrown, a 500.0 g ball goes from rest to a speed of 10.0 m/s over a distance of 0.75 m.  What is the force that was exerted on the ball?   Question 6 options:   A)  1.9 N   B)  3.3 N   C)  19 N   D)  33 N   E)  130 N

A 66 kg Man pushes off the 87kg Block on ice and slide away at a speed of 3 m/s. What is the speed of the block?

Consider the table.   Vehicle 1 Vehicle 2 Vehicle 3 Vehicle 4 Mass (kg) 1000 2000 1000 2000 Velocity (m/s) 20 20 40 40 Kinetic energy (kJ) 200 400 800 1600 The table shows data collected for some vehicles on the road. What conclusion can be drawn about the relationship between mass, velocity, and kinetic energy?   Answer Choices: a. If only the mass of the vehicle doubles, the kinetic energy increases by a factor of four. b. If both the mass and the velocity of the vehicle double, the kinetic energy will increase by a factor of eight. c. If only the velocity of the vehicle doubles, the kinetic energy will double. d. If both the mass and the velocity of the vehicle double, the kinetic energy will increase by a factor of four.

Sara throws a baseball to Janice. The baseball has a mass of 0.142kg. It is 1.1m above the ground, moving at 15m/s when sara lets go of it. Ignore the effects of air resistance. The baseball is moving horizontally at 13m/s when it reaches maximum height. Calculate the maximum height reached by the baseball.

Sometimes, steep roads going down have a small safety road by the side that goes up, which vehicules can use in an emergency, to slow down. A 3362.6 kg truck has lost its brakes coming down a mountain. Fortunately, there is a ramp of thick gravel inclined at 14 degrees that the driver can use to stop the truck. The truck hits the ramp moving at 20.58 m/s and then travels 35.6 meters up the ramp before it comes to a stop. What work is done by the gravel to stop the truck?

Marisa pushes a 1.635 kg book across a table, accelerating it at a rate of 2.099 m/s^2 over a time period of 1.891 s. If 2.760 watts of power were used to move the book, what distance does the book travel across the table?

A 2.0 kg object is moving to the right with a speed of 1.0 m/s when it experiences the force shown in the figure. What are the object’s speed and direction after the force ends? Express your answer to two significant figures and include the appropriate units. Enter positive value if the speed is directed to the right and negative value if the speed is directed to the left.
