Question

Give me some physics force numericals.

Answer 1

Answer:

1 How much net force is required to accelerate a 1000 kg car at 4.00 m/s2?

2.If you apply a net force of 3 N on .1 kg-box, what is the acceleration of the box?

3. Two objects of masses of 100 gm and 200 gm are moving in along the same line and direction with velocities of 2 ms-1 and 1 ms-1 respectively. They collide and after collision, the first object moves at a velocity of 1.67 ms-1. Determine the velocity of the second object?

4.A bullet of mass 10 gm is fired with an initial velocity of 20 m/s from a rifle of mass 4 kg. Calculate the initial recoil velocity of the rifle?

5. A car start from rest and acquire a velocity of 54 km/h in 2 sec. Find

(i) the acceleration

(ii) distance travelled by car assume motion of car is uniform

(iii) If the mass of the car is 1000 Kg,what is the force acting on it?
