A 20-ton truck collides with a 1500-lb car and causes a lot of damage to the car. During the collision:

A. the force on the truck due to the collision is slightly greater than the force on the car.

B. the force of on the truck due to the collision is exactly equal to the force on the car.

C. the car and the truck have the same magnitude acceleration.

D. the force on the car due to the collision is much greater than the force on the truck.

B. the force of on the truck due to the collision is exactly equal to the force on the car.

Explanation:

At the time of collision between two objects of unequal or equal masses  two forces emerge at the point of collision .They are called action and reaction force . According to third law of Newton , they are equal . So in the instant case of collision between car and truck , force on both of them  will be equal.

the speed of the cart after 3 seconds of low fan speed is ⇒ 54.0 cm/s.

the speed of the cart after 5 seconds of medium fan speed is ⇒ 120.0 cm/s.

the speed of the cart after 2 seconds of high fan speed is ⇒ 64.0 cm/s. 

just did the lab.

no
