Answer:
(472i + 80.3j) m
Explanation:
Given the following :
Distance of tee shot = 300m
Distance of second shot = 189.0 m
Displacement r1 of tee shot :
r1 = 300 mi
Displacement r2 of second shot :
r2 = 172.0 mi + 80.3 mj
The final displacement of the golf ball from the tee:
r_final = r1 + r2
r_final = (300i)m + (172.0i + 80.3j) m
r_final = (300 + 172)i m + 80.3j m
r_final = (472i + 80.3j) m

Answer:B
Explanation:The earth will keep moving unless acted up on by a force.
48J
Explanation:
Given parameters:
Weight of the book = 16N
Height of the shelf = 3m
Unknown:
Work done to raise the book = ?
Solution:
Work done is defined as the product of force and distance. The force here is the weight of the book which signifies that it was carried in the vicinity of gravitational force.
Work done = Force x distance = weight x distance
Weight is a type of force;
Input the parameters;
Work done = 16 x 3 = 48J
The unit of workdone is in Joules

Answer:
12.974 m/s
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
g = Acceleration due to gravity = 9.81 m/s²
= Coefficient of friction =0.66
a = Acceleration = 

Car's original speed before braking was 12.974 m/s
