______ hp

A 1.50 ✕ 103-kg car starts from rest and accelerates
uniformly to 15.1 m/s in 12.7 s. Assume that air resistance remains
constant at 400 N during this time.
(a) Find the average power developed by the engine. (hp)
(b) Find the instantaneous power output of the engine at t

A car at the Indianapolis 500 accelerates uniformly from the pit
area, going from rest to 330 km/h in a semicircular arc with a
radius of 230 m
A) Determine the tangential and radial acceleration of the car
when it is halfway through the arc, assuming constant tangential
acceleration.
B) If the curve were flat, what would the coefficient of static
friction would be necessary between the tires and the road to
provide this acceleration with no slipping or skidding?

A 1,500 kg car starts from rest and accelerates to 23 m/s in 11
s. Assume that the air resistance remains constant at 162 N.
Calculate the acceleration of the car.
Calculate the average force exerted by engine during this time.
Calculate the average velocity of the car.
Calculate the average power output during this time.

a. A toy car is accelerated from rest to 0.620 m / s in 20.0 ms.
The mass of the cart is 560 g. Determine the average power applied
to the cart.
b. An elevator with 8.00 x 102 kg of mass hangs from a cable.
The elevator accelerates downward at a rate of 1.80 m / s2.
Determine the cable tension.

a) A car accelerates uniformly from rest and reaches a speed of
13.7 m/s in 10.9 s. The diameter of a tire is 71.8 cm. Find the
number of revolutions the tire makes during this motion, assuming
no slipping. Answer in units of rev.
b) What is final rotational speed of a tire? Answer in units of
rev/s.

A car accelerates uniformly from rest and reaches a speed of

motion, assuming that no slipping occurs.
rev
(b) What is the final angular speed of a tire in revolutions per
second?
rev/s

1.Imagine two balls colliding on a billiard table that is
frictionless. Decide which statement is correct and explain why:(a)
The total momentum of the system that contains only one of the two
balls is the same before and after the collision.(b) The total
momentum of the system that contains both of the two balls is the
same before and after the collision.
2.One object is at rest, and another is moving. The two collide
in one-dimensional, completely inelastic collision. In...
