The motor of a 1.8 kg battery-powered toy car creates a constant force of 0.17 N in the direction of motion. If the car starts from rest, then what is its speed after 1.1 m of forward motion? (You may assume no friction.) Group of answer choices

0.75 m/s

0.32 m/s

0.46 m/s

0.21 m/s

4.8 m/s

1 - wave length

2 - amplitude

3 - crest

4 - trough

explanation:

duh.

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
