Question

What is the mass of an object if a force of 17N causes it to accelerate at 1.5 m/sec/sec

A. 11.38
B. 11.3 kg
C. 12.3 kg
D. 14.3 kg

Answer 1

B.11.3 kg

Explanation :

F=ma here force is given as 17N and acceleration as 1.5 m/sec/sec using the formula mass can be calculated

∴ F=ma

17N =m × 1.5 m
`s^(-2)`

`m=(F)/(a)`

`m= (17 kg m/sec/sec)/(1.5 m/sec/sec)`

∴ m=11.3 kg
