You wake up one morning to find yourself in a strange room with opaque walls, and no visible doors or windows. You decide to do some experiments to find out more about your strange situation. Your own body mass is 66.5 kg. You pick up an object and drop it from rest, starting at a height of 1.02 meters above the floor, and it hits the floor 0.274 seconds later. You can ignore air resistance. Based on the outcome of this experiment, when you step on the scale provided for you, what weight will it register for your body?

A brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 740 N on him. The mass of the losing player plus equipment is 88 kg, and he is accelerating at 1.8 m/s2 backward. Randomized Variables: f = 740 Nm1 = 88 kgm2 = 118 kga = 1.8 m/s2                                                        1. What is the magnitude of the force of friction, in newtons, between the losing player's feet and the grass as he slides backwards? F1 =                           2. What is the magnitude of the force, in newtons, that the winning player exerts on the ground to move forward if his mass plus equipment is 118 kg? Assume the second player has the same acceleration as the first. F2=

Please answer question 1, there is no diagram

A clever coyote uses rocket powered skates to try to catch a roadrunner. The mass of the coyote is 38.1 kg.If the coyote starts from rest, and accelerates to a final speed of 26 m/s in a distance of 2.4 m. How fast is the coyote moving when he has traveled 2.11m while he is slowing down? Assume his initial speed when he is slowing down is equal to his final speed when the rockets were firing.

A child riding a bicycle has a total mass of 30.6 kg. The child approaches the top of a hill that is 27.9 m high 27.9 and is 86.8 m (ℓ)  long at 12.1 m/s. If the force of friction between the bicycle and the hill is 26.7 N, what is the child's velocity at the bottom of the hill? (Disregard air resistance, g = 9.8 m/s2.)

Training is over, and the zombie apocalypse is upon us. You are at the top of a 50-m-high hill. A zombie horde is amassing at the bottom of the hill. You release the brakes on a 4500-kg car parked at the top of the hill to send it driving in to the horde. If the zombies are packed in tight and provide a resistive ”frictional force” of 8 × 104 N, how far does the car make it through the horde before coming to a stop?

A physics student, in a stationary elevator, places a 240.0 g mass on an electronic balance. The student hits the elevator button and it begins to move upwards. While the elevator is moving, the student records this information Time = 0 to 3.0 sec the balance reads 278 grams Time = 3.0 - 12 sec the balance reads 240. grams Time = 12.0 to 15.0 sec the balance reads 192 gram How far up (in meters) did the elevator travel? Consider: UP to be (+), DOWN to be (-) and g =9.8 m/s2 .  ROUND YOUR ANSWER TO A WHOLE NUMBER of meters (no decimal places) HINT: This problem requires finding THREE different displacements and adding them up! 2nd HINT:  You will need to (A) use your equations of motion or (B) make a v-t graph to find those displacements!

The final set of this lab has you hanging an unknown mass on a spring (for which you have determined the spring constant, k). If you find the spring constant k = 24.0 N/m, what is the mass of an unknown object if it displaces the spring 4.40 cm? Give your answer in GRAMS to 3 significant figures

A 110 g ball bobbing up and down on the ocean as the waves roll by has a vertical position that can be described as a function of time by x(t)=cos(10t). What is the force on the ball at a time of 5.4 seconds?

The coefficient of friction between the wheels of Yamaha motorcycle and the dry pavement is 0.88. An animal walks out into the road, causing a motorcyclist to slam on the brakes. The wheels stop turning, but the tires skid along the road, causing intense friction and heat. Determine the magnitude (positive) of the acceleration which the 224-kg motorcycle experiences while skidding to a stop. The mass includes the rider. Answer: m/s/s (or m/s²)
