Answer:
89.2
Step-by-step explanation:
57.2+32=89.2
2x² - 3xy
2(1)² - 3(1)(2)
2(1) - 3(2)
2 - 6
-4
Answer:
49N
Step-by-step explanation:
Step one
Given
When the force of 63 N acts on a certain object
the acceleration of the object is 9/ms^2
Firstly, we need to calculate the mass m
F=ma-------1
m= F/a
m= 63/9
m= 7kg
Step two:
Also, if the acceleration of the object becomes 7 m/s^2
then the force
Note: the mass remains the same= 7kg
F=ma
F=7*7
F= 49N
