Q1. You're driving down the highway late one night at 20 m/s while a deer steps onto the road 44m in front of you. Your reaction time before stepping on the brakes is 0.50 s, and the maximum deceleration of your car is 11m/s^2 .How much distance is between you and the deer when you come to a stop?
Q2. A man drags a table 4.30 m across the floor, exerting a constant force of 55.0 N, directed 26.0° above the horizontal.
(a) Find out the work done by the applied force.
(b) How much work is completed by friction? Suppose the table's velocity is constant.
A superhero flies 147 m from the top of a tall building at the angle of 33 degrees below the horizontal. What is the vertical component of the superhero's displacement.

A 1.2µF capacitor is charged to a potential difference of 11.0V. The wires connecting the capacitor to the battery are next disconnected from the battery and connected across a second, initially uncharged, capacitor. The potential difference across t..
A particle undergoes a displacement Δr of magnitude 57 m in a direction 25° below the x axis. Express Δr in terms of the unit vectors x and y.
The collar C is moving downward with an acceleration of 1 m/s2. At the instant shown, it has a speed of 2 m/s which gives links CB and AB an angular velocity ωAB = ωCB = 10 rad/s. Determine the angular accelerations of CB and AB at this instant.
A bumper car with mass m1 = 115kg is moving to the right with a velocity of v1 = 4 m/s. A second bumper car with mass m2 = 95 kg is moving to the left with a velocity of v2 = -3.7 m/s. The two cars have an elastic collision. Suppose the surface is fr..

Use the binomial expansion to find an approximate expression
A copper telephone wire has essentially no sag between poles 20.5 meters apart on a winter day while the temperature is -15.5° C. How much longer is the wire on the summer day when the temperature is 27.0° C.
On a cool morning, when the temperature is 16.0 ^circC, you measure the pressure in your car tires to be 20.0 psi. After driving 30.0mi on the freeway, temperature of your tires is 51.0 ^circC.
Find the position of the object to acquire real, magnified image, inverted, and virtual, upright image.
Two point charges = 2.10 and = -6.40 are 0.100 apart. Point is midway between them; point is 0.080 from and 0.070 from. Take the electric potential to be zero at infinity.
