Solving with the Speed equation: v= d/t (add to notes if desired)
3. Juan has ridden his bike a total distance of 20 km. If his average speed was 15km/h,
how much time did he ride for?
a)
What is given in the problem? (Circle)
b) What are we trying to find? (Square)
What will be the units to our solution?
d) Plug into the speed equation and solve.

The motor m applies a time-varying force of f (200 t) n, where t is in seconds. box b with mass 200 kg starts from rest, and the coefficients of kinetic and static friction are 0.2 and us 0.3 the acceleration due to gravity is g 9.8 m/s2 b 300 a) find the time ' when the box starts to move. b) calculate the speed of the crate at 3 s c) calculate the power delivered by the motor at t 3 s

In the first law of thermodynamics, triangle e=q-w, what does q stand for

While the change in blank will remain the same during a collision, the force needed to bring an object to a stop can be blank if the time if collision is blank
