Answer:
1. F = 50N
2. a = 1.5m/[tex]s^{2}[/tex]
3. m = 1.67 kg
Explanation:
1. a = 5m/[tex]s^{2}[/tex]
m = 10 kg
F = ?
[tex]F = ma\\F = (10kg)(5m/s^{2} )\\F = 50kgm/s^{2} \\F = 50N[/tex]
2. m = 20 kg
F = 30N
a = ?
[tex]a = \frac{F}{m} \\a = \frac{30N}{20kg} \\a = \frac{30kgm/s^{2} }{20kg} \\a= 1.5m/s^{2}[/tex]
3. F = 50N
a = 30 m/s
m = ?
[tex]m = \frac{F}{a} \\m = \frac{50N}{30m/s^{2} } \\m = \frac{50kgm/s^{2} }{30m/s^{2} } \\m = 1.67kg[/tex]
