A truck travels uphill with constant velocity on a highway with a 7.5° slope. A 30-kg package sits on the floor of the back of the truck and does not slide, due to a static frictional force. During an interval in which the truck travels 405 m, find the following.

(a) What is the net work done on the package? (J)

(b) What is the work done on the package by the force of gravity? (J)

(c) What is the work done on the package by the normal force? (J)

(d) What is the work done on the package by the friction force? (J)

A theme ride vehicle is moving uphill at a constant speed. The slope of the hill is 10○. The mass of the vehicle plus the riders is 2000 kg. The vehicle is powered by a WLIM (Wheeled Linear Induction Motor). The pole pitch of the motor is 0.5m. The friction coefficient of the surface is 0.01. The primary circuit resistance R1 is 0.5 Ω, and the secondary resistance referred to the primary circuit R2’ is 1.0 Ω. The equivalent inductance...

5a) A 5-kg object travels at a constant velocity of 25 m/s east on a smooth, frictionless surface. An 8-kg object travels at a constant velocity of 55 m/s west on the same surface and then collides directly with the 5 kg-object. The two objects stick together. What is the velocity of the two-object system, just after they collide and stick together? b) After a .20 kg street-hockey puck is hit, it has an initial velocity of 35 m/s and...

A car enters an onramp of a highway at 21.8 m/s and travels at a constant velocity for 3.63 s before speeding up to a final velocity of 32.1 m/s in 6.90 s to merge with highway traffic. The total time taken for the trip is 10.5 s. Assume the car doesn't have to change direction for this motion (1D motion). Draw a picture of this motion and create a coordinate system Please reverse the direction of your coordinate system....

Block 1 (0.5 kg) travels with an initial velocity of [ 40i ] + [ 60j ] m/s and then collides with block 2 (0.5 kg) traveling with an initial velocity of [ -40i ] + [ -40j ] m/s. After the collision, block 1 has a final momentum of [ 5i ] + [ -25j ] kg*m/s. Assume that no external forces are present and therefore the momentum for the system of blocks is conserved. What is the initial...

as a pick up truck travels along a level stretch of road with constant speed, most of the power developed by the engine is used to compensate for the energy transformation due to friction force is exerted on the pick up truck by the air in the road. If the power developed by the engine is 2.23 hp, calculate the total friction force acting on the pick up truck (in N) when it is moving at speed of 29 m/s....
