Answer #1

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 merry-go-round starts from rest and accelerates uniformly over
26.5 s to a final angular velocity of 6.90 rev/min.
(a) Find the maximum linear speed of a person sitting on the
merry-go-round 7.25 m from the center.
(b) Find the person's maximum radial acceleration.
(c) Find the angular acceleration of the merry-go-round.
(d) Find the person's tangential acceleration.

A merry-go-round starts from rest and accelerates uniformly over
19.5 s to a final angular velocity of 6.25 rev/min.
(a) Find the maximum linear speed of a person sitting on the
merry-go-round 4.00 m from the center.
(b) Find the person's maximum radial acceleration.
(c) Find the angular acceleration of the merry-go-round.
(d) Find the person's tangential acceleration.

A car starts from rest at a stop sign. It accelerates at 3.6
m/s^2 for 6.5 s, coasts for 1.7 s, and then slows down at a rate of
2.5 m/s^2 for the next stop sign.
How far apart are the stop signs?

1 point) A truck starts from rest and accelerates at
1?/?2. 6 s later, a car accelerates from rest at the
same starting point with an acceleration of
2.7?/?2.
a) Where and when does the car catch the truck?
1. ?m from the starting point
2. at ? seconds from the moment the truck started to
accelerate.
b) What are their velocities when they meet?
The truck : m/s
The car : m/s

A race car accelerates uniformly from a speed of 32 m/s to a
speed of 63 m/s in 5.1 s while traveling counterclockwise around a
circular track of radius of 422 m. When the car reaches a speed of
46 m/s, find the magnitude of the total acceleration (centripetal +
tangential acceleration) in m/s2.

An electric vehicle starts from rest and accelerates at a rate
of 2.1 m/s2 in a straight line until it reaches a speed
of 19 m/s. The vehicle then slows at a constant rate of 1.3
m/s2 until it stops. (a) How much time
elapses from start to stop? (b) How far does the
vehicle move from start to stop

A car starts from rest and accelerates at a constant rate
travelling a distance of 210 m in 14.9 s. The car continues to
accelerate at the same rate for an additional 199 m. What is the
speed (in m/s) of the car after it has travelled the (210+199)
m?

A car accelerates uniformly from rest to 17.9 m/s in 6.31 s
along a level stretch of road. Ignoring friction, determine the
average power required to accelerate the car if (a) the weight of
the car is 8.28 x 103 N, and (b) the weight of the car is 1.58 x
104 N.

3. A helicopter travelling at a velocity of 15 m/s [W]
accelerates uniformly at a rate of 7.0 m/s2 [E] for 4.0 s. What is
the helicopter’s final velocity?
4. Two go-carts, A and B, race each other around a 1.0
km track. Go-cart A travels at a constant speed of 20.0 m/s.
Go-cart B accelerates uniformly from rest at a rate of 0.333 m/s2 .
Which go-cart wins the race and by how much time?
5. A boat increases...
