Atruck is traveling horizontally to the right. when the truck starts to slow down, the crate on the (frictionless) truck bed starts to slide. in what direction could the net force be on the crate?
a. straight up (the normal force).
b. horizontal and to the left.
c. straight down (because of gravity).
d. horizontal and to the right.
e. no direction. the net force is zero.
126,144,000 should be your answer.
it is when it loses electrons
our weight on moon is less than it would be on earth due to a difference of the strength of gravity on the moon. the moon's gravitation force is determined by the mass and the size of the moon. since the moon has significantly less mass than the earth, it will not pull objects toward itself at the strength that earth will. this means that if you went to the moon you would weigh less, even though your mass stays the same.
since the car is going 10m/s already just put that aside.
accelerating at a rate of 3m/s for 4 seconds
12+10= 22m/s is the final velocity
