Question

A solar sail is a large sheet of light-reflecting plastic spread on an extremely low-mass framework and attached to a spacecraft. Sunlight exerts a force on the sail and moves the spacecraft. Suppose the spacecraft has a total mass of 100kg (including the sail) and sunlight exerts a total force of 2N on the sail. What will be the acceleration of the spacecraft? O A 50m/s2 O B 0.02m/s2 OC100m/s O D 2m/s. ○ E 0.2m/s r7 Fullscreen
A horse is pulling a cart along a road. Which of the following pairs of forces is an action-reaction pair? O A The force of the horse on the cart and the force of the road on the horse. O B The brce of the horse on the cart and the force of the horse on the road. O C The force of horse on the road and the force of the road on the horse. 0 D The force of the cart on the horse and the force of the horse on the road. OE The force of the cart on the horse and the force of the road on the horse.
The recoil or kick of a gun that is firing a bullet is a force exerted on the gun by 0 A the gun itself. 0 B the air around the gun. ° C the bullet. O D the inertia of the gun OE the hand of the shooter

Answer #1

m = mass of the spacecraft = 100 kg

F = total force on the spacecraft = 2 N

a = acceleration of the spacecraft = ?

using newton's second law

F = ma

2 = 100 a

a = 2/100 = 0.02 m/s2

so correct choice is B

B The brce of the horse on the cart and the force of the horse on the road. ° C The force of horse on the road and the force of the road on the horse.

C, By the bullet
