Answer:
Explanation:
Change in velocity considering the x component will be
Final velocity-Initial velocity
Change in velocity considering the y component will be
Final velocity-Initial velocity
Resultant change in velocity
Acceleration= change in velocity per unit time hence
Using the formula F = m*a. where F is the force, m is the mass and a is the acceleration you can use it for each. As long as there are no other forces towards the body in both cases :
F = m*a
F = 50*3
F = 150 N
Answer:
the correct answer is D
Explanation:
In this exercise, the vectors are in the same west-east direction, so we can assume that the positive direction is east and perform the algebraic sum.
R = δ + ε
where
δ = 2.0 m
ε = 7.0 m
the positive sign indicates that it is heading east
R = 2.0 + 7.0
R = 9.0 m
the direction is east
the correct answer is D
7500m because 1,500 in 1 sec so 1500x5 7500
