Answer:
By order:
21. a = F/m
F = 52N m = 4kg
a = 52N/4kg a = 52kg(m/s^)/4kg
a = 13 m/s^2
Answer: The acceleration of the object is 13m/s^2
22. a = F/m
F = 61N m = 5kg
a = 61N/5kg a = 61kg(m/s^2)/5kg
a = 12.2 m/s^2
Answer: The acceleration of the object is 12.2 m/s^2
23. a = F/m
F = 300N m = 25kg
a = 300N/25kg a = 300kg(m/s^2)/25kg
a = 12 m/s^2
Answer: The acceleration is 12 m/s^2
24. F = ma
m = 10kg a = 2m/s^2
F = (10kg)(2m/s^2)
F = 20N
Answer: The force required is 20N
35. m = F/a
F = 17N a = 1.5m/s^2
m = 17N/1.5m/s^2 m = 17kg(m/s^2)/1.5m/s^2
m = 11.3 kg
Answer: The mas of the object is 11.3kg
36. a = F/m
F = 3N m = 10kg
a = 3N/10kg a = 3kg(m/s^)/10kg
a = 0.3m/s^2
Answer: the acceleration of the object is 0.3m/s^2
Hope this helps!
