A car travels 25.0 km of a 50.0 km trip at an average speed of 40.0 kmh–1 . It travels the second half of its journey at an average speed of 80.0 kmh–1. A truck makes the same trip but spends half of its time at an average speed of 40.0 kmh–1 and the other half of its time at an average speed of 80.0 kmh–1. Which vehicle got there in the shortest period of time? Show your work
f the magnitude of the resultant force is to be 9kN directed along the
positive x axis, determine the magnitude of force T acting on the eyebolt
and its angle delta.
Suppose we are told that the acceleration (a) of a particle moving with uniform speed (v)
in a circle of radius (r) is a=kr^ n v^ prime
Determine the values of n and m and write the simplest form of this equation.
Note: K is a dimensionless constant

A man lifts a mass of 3kg upwards through 2m. If g=10m/s2 calculate work done
A block of cherry wood that is 20.0 cm long, 10.0 cm wide, and 2.00 cm thick has a density of 800. kg/m3. What is the volume of a piece of iron that, if glued to the bottom of the block, makes the block float in water with its top just at the surface of the water? The density of iron is 7860 kg/m3, and the density of water is 1000. kg/m3.
How much potential energy does a car gain if a crane lifts the car with a mass of 1,500 kg and 20 m straight up
List all the forces that act on you while you are standing on the ground.

Two asteroid s are drifting away from each other.One asteroid have mass of 240000 kg. and the other has a mass of 100000 kg. What is the change in gravitational potential energy as their center s of the mass move from 100 m apart to 1000 m apart?
the 50-kg, uniform crate slides down the inclined surface with an initial speed 10 m/s. if the coefficient of kinetic friction between the crate and the inclined surface is 0.15, determine the distance s the crate has moved when it momentarily stops. (Assume tipping over does not happen)
