An automobile weighing 15000n crashes into a wall with a velocity of 5m/sec. If the car moves .15m before coming to a stop, what average force does the car exert? on the wall?

a 20kg box is pulled across ahorizontal surface with aforce of 100nt. The coefficient of friction is .3 (a) find the acceleration. (b) how far will the box move in 5 sec. (c) What is the velocity at this time?

A proton (mass=1.67*10^-27 kg) moves with a velocity of 6.00*10^6 m/sec. Upon colliding with a stationary particle of unknown mass, the proton rebounds upon its own path with a velocity of 4.00*10^6 m/sec. The collision sends the unknown particle forward...

The air mattress exerts the same impulse, but a smaller net average force, on the high-jumper than does the hard ground.

PQR and PRQ are right angles PQR and PRQ are obtuse angles the sum of the measures of PQR and PRQ is 45 degrees The sum of the measure of PQR and PRQ is 135 degrees

so 45 degrees? does anyone have second thoughts? If you know the answers to the rest of the question please put them here? please put them here!!!!!!!!!!!!!!! it is Lesson 13: Geometry Unit Test Math 7 B Unit 1: Geometry

oh? Im sorry ma'am! I just don't understand this and I need help with the rest of the test!

ohhhhhhhh um...…. yes ma'am.

Its called the "old stage" In this stage the gradients are gentle and the velocity is low. Accordingly the river lose most of its erosive power and flow in a sluggish manner. In old age a river has maximum meandering. The river at this age does little of...

i'm sad for bruh

ms sue know more than all of us stop being children
