a 7.9 kg block is placed on an inclined plane that is 29 degrees from the horizontal.
what is the acceleration of the block? ignore friction.

4.8 m/s²

Explanation:

Draw a free body diagram.  There are two forces:

Weight force mg pulling down

Normal force N pushing perpendicular to the incline

Sum the forces in the parallel direction:

∑F = ma

mg sin θ = ma

a = g sin θ

a = 9.8 m/s² sin 29°

a = 4.8 m/s²

the total distance traveled by the car is

30km + 49km = 79 km .

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
