2.A 20 N unbalanced force causes an object to accelerate at 1.5 m/s2. What is the mass of the object?
3. An unbalanced force of 500 N is applied to a 75 kg object. What is the acceleration of the object?
4.A man pushes his child in a grocery cart. The total mass of the cart and child is 30.0 kg. If the force of friction on the cart is 15.0 N, how hard does the man have to push so that the cart accelerates at 1.50 m/s²?
5. A 3.00 kg cart on a frictionless track is pulled by a string so that it accelerates at 2.00 m/s2. What is the tension in the string?

Answer:
2.As per Newton's II law we know that
F = maF=ma
here we know that
F = 20 NF=20N
a = 1.5 m/s^2a=1.5m/s
2
now the mass of the object will be given as
m = \frac{F}{a}m=
a
F
m = \frac{20}{1.5}m=
1.5
20
m = 13.3 kgm=13.3kg
so mass of the object will be 13.3 kg
3.Answer:
Acceleration, a=6.66\ m/s^2a=6.66 m/s
2
Explanation:
Given that,
Force acting on the object, F = 500 N
Mass of the object, m = 75 kg
We need to find the acceleration of the object. The force acting on the object is given by :
a=\dfrac{F}{m}a=
m
F
a=\dfrac{500\ N}{75\ kg}a=
75 kg
500 N
a=6.66\ m/s^2a=6.66 m/s
2
So, the acceleration of the object is 6.66\ m/s^26.66 m/s
2
. Hence, this is the required solution.
